Solving For X: A Step-by-Step Guide To 6 - 4x = 7x - 9x - 4
Hey guys! Ever get stuck on a math problem that looks like it's written in another language? Don't sweat it! Today, we're going to break down a classic algebra problem step-by-step, so you can tackle similar questions with confidence. We'll be focusing on solving for x in the equation 6 - 4x = 7x - 9x - 4. Sounds intimidating? Trust me, it's not as scary as it looks. We'll go through each step nice and slow, so grab your pencil and paper, and let's get started!
Understanding the Equation
Before we dive into the solution, let's quickly understand what this equation is all about. In essence, we're looking for a value of x that makes both sides of the equation equal. Think of it like a balancing scale: we need to find the x that keeps the scale perfectly balanced. The left side of the equation is 6 - 4x, and the right side is 7x - 9x - 4. Our goal is to isolate x on one side so we can figure out its value. Remember those days in math class when algebra seemed like a different language? Well, today we're fluent! We're going to transform this equation from a jumble of numbers and letters into a clear, understandable solution. Stick with me, and you'll see how algebra is just a puzzle waiting to be solved. Understanding the equation is the first crucial step because it sets the foundation for everything else we'll do. Without a clear grasp of what we're trying to achieve, the subsequent steps can feel confusing. So, before moving on, make sure you're comfortable with the idea that we're seeking the 'x' that makes both sides of this equation perfectly balanced.
Step 1: Simplify Both Sides of the Equation
Okay, first things first, let's simplify each side of the equation separately. This will make our lives much easier down the road. On the left side, we have 6 - 4x. There's not much to do here since 6 and -4x are different terms (one's a constant, the other has an x), so we'll leave it as is. Now, let's tackle the right side: 7x - 9x - 4. Aha! We can combine the x terms here. Think of it as having 7 x's and then taking away 9 x's. What are we left with? That's right, -2x. So, the right side simplifies to -2x - 4. Now our equation looks a little cleaner: 6 - 4x = -2x - 4. See? Already less intimidating! Simplifying both sides is like decluttering your workspace before starting a project. By tidying up the equation, we make it easier to see the path forward. We've reduced the number of terms and made the equation more manageable. This is a fundamental strategy in algebra: always look for opportunities to simplify before moving on to more complex operations. Remember, math isn't about making things harder; it's about finding the most efficient way to reach the solution. So, with our simplified equation in hand, we're ready to move on to the next step and get closer to unlocking the value of x.
Step 2: Group the x Terms on One Side
Alright, time to get those x terms all cozy together on one side of the equation. Our goal here is to isolate x, remember? We have 6 - 4x = -2x - 4. Let's move the -4x term from the left side to the right side. To do this, we'll add 4x to both sides of the equation. Why add? Because adding 4x to -4x cancels them out on the left! This gives us: 6 - 4x + 4x = -2x - 4 + 4x. Simplifying this, we get 6 = 2x - 4. Notice how the x term is now only on the right side? We're making progress! Grouping the x terms is a key step in solving for x. It's like gathering all your ingredients in one place before you start cooking. By bringing all the x terms together, we set ourselves up to isolate x and find its value. This step often involves using the addition or subtraction property of equality, which simply means that we can add or subtract the same value from both sides of the equation without changing its balance. It might seem like a small step, but it's a crucial one in the journey towards solving for x. With our x terms grouped together, we're one step closer to the solution. So, let's keep the momentum going and move on to the next stage of our algebraic adventure!
Step 3: Isolate the x Term
Now, let's isolate that 2x term on the right side. We have 6 = 2x - 4. To get the 2x by itself, we need to get rid of that -4. How do we do that? You guessed it – we'll add 4 to both sides of the equation! This gives us: 6 + 4 = 2x - 4 + 4. Simplifying this, we get 10 = 2x. Look at that! The 2x is almost completely isolated. We're in the home stretch now! Isolating the x term is like clearing the final obstacles on a race track. We've navigated the simplification and grouping steps, and now we're focused on getting x completely on its own. This often involves using the addition or subtraction property of equality, just like we did in the previous step. The key is to identify any terms that are interfering with the x term and then use the opposite operation to eliminate them. By isolating the x term, we bring the solution into clear view. It's like zooming in on a target – we're getting a much clearer picture of what the value of x actually is. So, with the x term almost completely isolated, we're ready for the final step that will reveal the answer!
Step 4: Solve for x
Okay, the grand finale! We have 10 = 2x. To finally solve for x, we need to get rid of that 2 that's multiplying x. The opposite of multiplication is division, so we'll divide both sides of the equation by 2. This gives us: 10 / 2 = 2x / 2. Simplifying, we get 5 = x. Woohoo! We did it! We found the value of x. It's 5. That wasn't so bad, right? Solving for x is the ultimate goal of this algebraic journey. It's the moment when all the previous steps come together and reveal the answer we've been seeking. This final step often involves using the division or multiplication property of equality, which is the counterpart to the addition and subtraction property we used earlier. The key is to identify the operation that's linking the coefficient to x and then use the opposite operation to undo it. By solving for x, we've not only found the solution to this specific equation but also honed our algebraic skills for tackling future challenges. So, let's take a moment to celebrate our success and then reflect on the journey we've taken to get here!
