Understanding the Equation
Before we jump into solving, let's first understand the equation: (6-1)x3=x...)-(3x). Understanding the components of the equation is crucial. It's like having a map before starting a journey; it gives you direction and context. In this equation, we have numbers, variables (x), and mathematical operations such as subtraction, multiplication, and potentially division (implied by the structure). The variable 'x' represents an unknown value we're trying to find. The equation essentially states that the expression on the left side is equal to the expression on the right side. Our goal is to manipulate the equation using algebraic principles to isolate 'x' on one side, thereby revealing its value.
We'll start by simplifying each side of the equation. This involves performing the operations within the parentheses first, then dealing with multiplication and any other operations present. Remember the order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This order is the golden rule in simplifying mathematical expressions. By carefully following these steps, we can break down the complexity of the equation and make it more manageable. Recognizing the structure and components of the equation is the first step toward solving it effectively.
Step-by-Step Solution
Okay, guys, let's get to the nitty-gritty of solving this equation. Here’s how we’ll tackle it step-by-step:
1. Simplify the Left Side
First, let's simplify the left side of the equation: (6-1)x3. According to the order of operations, we start with the parentheses. So, 6-1 equals 5. Now we have 5x3. Multiplying 5 by 3 gives us 15. Therefore, the left side of the equation simplifies to 15. This is a straightforward application of basic arithmetic, but it's crucial to get it right. Simplification is the key to making complex equations more manageable. By breaking down the equation into smaller, more digestible parts, we reduce the chances of making errors and gain a clearer understanding of the problem. This initial simplification sets the stage for the rest of the solution process.
2. Simplify the Right Side
Now, let's tackle the right side: x...)-(3x). It seems there might be a slight typo here, which is common in math problems! I assume that the correct equation is x - (3x). Assuming that, we can proceed with the simplification. We have x minus 3 times x. To simplify this, we can think of 'x' as '1x'. So, we have 1x - 3x. Subtracting 3x from 1x gives us -2x. Thus, the right side simplifies to -2x. It’s important to pay attention to the signs (positive or negative) when combining like terms. A small mistake in the sign can lead to a completely different answer. Simplifying algebraic expressions often involves combining like terms, which are terms that have the same variable raised to the same power.
3. Rewrite the Equation
Now that we’ve simplified both sides, let's rewrite the equation. The left side simplified to 15, and the right side (assuming the correction) simplified to -2x. So, our equation now looks like this: 15 = -2x. See how much simpler it looks now? This is the power of simplification! By reducing the complexity of the equation, we’ve made it much easier to see the next steps. Rewriting the equation in its simplified form is a crucial step in solving for the unknown variable. It allows us to focus on isolating the variable without being distracted by unnecessary clutter.
4. Isolate x
Our next goal is to isolate 'x' on one side of the equation. We have 15 = -2x. To get 'x' by itself, we need to get rid of the -2 that's multiplying it. We do this by performing the inverse operation, which is division. We'll divide both sides of the equation by -2. Remember, whatever we do to one side of the equation, we must do to the other side to maintain the balance. So, 15 divided by -2 is -7.5, and -2x divided by -2 is x. This gives us -7.5 = x, or x = -7.5. Isolating the variable is the heart of solving algebraic equations. It involves using inverse operations to undo the operations that are attached to the variable.
5. The Solution
So, guys, we've done it! We've found the value of x. The solution to the equation (6-1)x3=x...)-(3x) (assuming the correction x - (3x)) is x = -7.5. This means that if we substitute -7.5 for 'x' in the original equation, both sides of the equation will be equal. It’s always a good idea to double-check your answer by plugging it back into the original equation to make sure it works. This helps to catch any errors that might have occurred during the solution process. The solution represents the value of the unknown variable that satisfies the equation, making both sides equal.
Checking Our Work
To make sure we’re spot-on, let’s check our work. This is a super important step in solving any math problem. It’s like proofreading a paper before you submit it; you want to catch any mistakes. We’ll plug our solution, x = -7.5, back into the original equation (assuming the corrected version): (6-1)x3 = x - (3x). First, let's calculate the left side: (6-1)x3 = 5x3 = 15. Now, let's calculate the right side: -7.5 - (3 * -7.5) = -7.5 - (-22.5) = -7.5 + 22.5 = 15. Both sides equal 15, so our solution checks out! Checking your work not only verifies your answer but also reinforces your understanding of the problem and the solution process. It provides a sense of confidence in your mathematical abilities.
Common Mistakes to Avoid
Let’s chat about some common mistakes people make when solving equations like this. Knowing these pitfalls can help you steer clear of them! One common mistake is not following the order of operations (PEMDAS/BODMAS). Remember, parentheses first, then exponents, then multiplication and division, and finally addition and subtraction. Another mistake is making errors with negative signs. It’s easy to mix them up, especially when subtracting negative numbers. Always double-check your signs! Also, be careful when combining like terms. Make sure you're only combining terms that have the same variable and exponent. Finally, don’t forget to perform the same operation on both sides of the equation to maintain balance. Avoiding these common mistakes can significantly improve your accuracy and efficiency in solving algebraic equations.
