Solving The Equation (2x/3) + 1 = 3 A Step-by-Step Guide

Hey guys! Let's dive into this math problem together and figure out the correct value of 'x' in the equation (2x/3) + 1 = 3. It's like a puzzle, and we're the detectives, ready to crack the code. We'll break down each step, making it super clear and easy to follow. So, grab your thinking caps, and let's get started!

Breaking Down the Equation: A Step-by-Step Guide

When faced with an equation like (2x/3) + 1 = 3, it might seem a bit intimidating at first, but don't worry! We can tackle it piece by piece. The key is to isolate 'x' on one side of the equation. Think of it like unwrapping a present; we need to carefully peel away the layers to reveal the surprise inside – which, in this case, is the value of 'x'. Our main keyword here is solving equations, which is a fundamental concept in mathematics. Understanding how to solve equations opens doors to more advanced topics and real-world applications. It's like learning the alphabet before writing a novel; it's the building block for mathematical fluency.

First, we need to get rid of that '+ 1' that's hanging out on the left side of the equation. To do this, we perform the opposite operation, which is subtracting 1. But remember, in math, it's all about balance! What we do to one side of the equation, we must do to the other. So, we subtract 1 from both sides. This gives us (2x/3) = 2. See? We're already making progress! It's like clearing the first hurdle in a race; we're one step closer to the finish line. Each step we take is a small victory, building our confidence and solidifying our understanding. Now, we have a simpler equation to work with, and the path to finding 'x' is becoming clearer.

Next up, we need to deal with that fraction, 2x/3. Fractions can sometimes look scary, but they're really just another way of representing division. In this case, '2x' is being divided by 3. To undo this division, we do the opposite operation, which is multiplication. We multiply both sides of the equation by 3. This gives us 2x = 6. We're on a roll now! It's like climbing a ladder, each rung bringing us closer to the top. With each step, we simplify the equation and get closer to our goal of isolating 'x'. The feeling of accomplishment we get from solving each step motivates us to keep going and tackle more complex problems.

Finally, we have 2x = 6. This means that '2' times 'x' equals 6. To isolate 'x', we need to undo the multiplication. We do this by dividing both sides of the equation by 2. This gives us x = 3. Ta-da! We've found our answer! It's like reaching the summit of a mountain after a challenging climb; the view from the top is totally worth it. Finding the value of 'x' feels just as rewarding. We've successfully navigated the equation, step by step, and arrived at the solution. This process not only gives us the answer but also strengthens our problem-solving skills and builds our mathematical foundation. Remember, the journey of solving an equation is just as important as the destination. Each step teaches us something new and reinforces our understanding of mathematical principles.

Why x = 3 is the Correct Solution

So, we've arrived at x = 3, but let's double-check our work to make sure we're spot on. It's like proofreading an essay before submitting it; we want to ensure there are no errors. To verify our solution, we substitute 'x = 3' back into the original equation: (2x/3) + 1 = 3. This process of verification is crucial in mathematics. It's not enough to just find an answer; we need to confirm that it's correct. This step helps us catch any mistakes we might have made along the way and reinforces our understanding of the equation.

Substituting 'x = 3' gives us (2 * 3 / 3) + 1 = 3. Now, we simplify the left side of the equation. First, we multiply 2 by 3, which gives us 6. So, we have (6/3) + 1 = 3. Next, we divide 6 by 3, which gives us 2. Now our equation looks like this: 2 + 1 = 3. Finally, we add 2 and 1, which equals 3. So, we have 3 = 3. Bingo! The left side of the equation equals the right side. This confirms that our solution, x = 3, is indeed the correct answer. It's like fitting the last piece of a jigsaw puzzle; everything clicks into place, and the picture is complete. This verification process gives us confidence in our solution and reinforces our understanding of the equation.

Now, let's think about those other options that were presented: x = 6, x = 2 2/3, and x = 1 1/3. We can quickly see why these are incorrect by plugging them into the original equation. For example, if we try x = 6, we get (2 * 6 / 3) + 1 = 5, which is not equal to 3. Similarly, if we try the other incorrect options, they won't satisfy the equation. This exercise highlights the importance of following the correct steps and performing the operations in the right order. It's like following a recipe; if we skip a step or use the wrong ingredients, the final dish won't turn out as expected. Each step in solving an equation is crucial, and verifying our solution ensures that we haven't made any mistakes.

Common Mistakes to Avoid When Solving Equations

Solving equations can be tricky, and it's easy to make mistakes if we're not careful. It's like navigating a maze; there are many paths, but only one leads to the exit. Let's talk about some common pitfalls to watch out for, so we can become equation-solving pros! Our keyword here is common mathematical errors, which is a crucial aspect of learning mathematics. Understanding where mistakes can occur helps us develop strategies to avoid them. It's like knowing the common hazards on a hiking trail; we can prepare ourselves and navigate the trail more safely.

One frequent mistake is forgetting to perform the same operation on both sides of the equation. Remember, an equation is like a balanced scale; if we add or subtract something on one side, we need to do the same on the other side to maintain the balance. Failing to do this throws the equation off, and we'll end up with the wrong answer. It's like trying to build a tower with uneven blocks; the tower will be unstable and likely to collapse. Maintaining balance in an equation is crucial for finding the correct solution.

Another common error is mishandling the order of operations. We need to follow the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to ensure we're performing the operations in the correct sequence. It's like following a set of instructions; if we skip a step or do them in the wrong order, the outcome won't be as expected. Forgetting the order of operations can lead to incorrect calculations and a wrong answer.

Sign errors are also a common culprit. A simple mistake like dropping a negative sign can completely change the outcome of the equation. It's like misplacing a decimal point; a small error can have a significant impact on the result. We need to be extra careful when dealing with negative numbers and double-check our signs at each step.

Finally, not simplifying the equation before solving it can make the process more complicated and increase the chances of making a mistake. It's like trying to untangle a knot; it's easier to work with if we simplify it first. Simplifying the equation by combining like terms and reducing fractions makes the equation easier to solve and reduces the likelihood of errors. By being aware of these common mistakes, we can develop strategies to avoid them and become more confident and accurate equation solvers.
