Hey there, math enthusiasts! Today, we're diving into a fun little equation to uncover the value of 'n'. We've got the equation 2 * n * 5 = 30, and our mission is to figure out what number 'n' represents. Don't worry, it's not as daunting as it might seem. We'll break it down step by step, making it super easy to follow. So, grab your thinking caps, and let's get started!
Decoding the Equation: 2 * n * 5 = 30
When we first glance at an equation like 2 * n * 5 = 30, it might look a bit intimidating, especially with that 'n' hanging out in the middle. But fear not! Equations are simply mathematical puzzles, and we're the puzzle solvers. Let's dissect this equation to understand what it's really saying. The equation is essentially telling us that if we multiply 2 by a certain number ('n') and then multiply the result by 5, we'll end up with 30. Our job is to figure out what that 'certain number' is. Think of 'n' as a placeholder, a mystery number that we're trying to identify. The beauty of math lies in its logic and consistency, so there's definitely a way to find the solution. We just need to apply the right steps.
Simplify and Conquer
The first step to solving this equation is to simplify it. We can make things easier by combining the numbers we already know. In this case, we have 2 and 5 being multiplied together. So, let's do that first. 2 multiplied by 5 is 10. Now, our equation looks a lot simpler: 10 * n = 30. See? We've already made progress! By simplifying the equation, we've reduced the number of operations we need to deal with, making it much clearer what we need to do next. Remember, simplification is a powerful tool in math. It allows us to break down complex problems into smaller, more manageable steps. This not only makes the problem easier to solve but also helps us understand the underlying relationships between the numbers and variables involved.
Isolating 'n': The Key to the Solution
Now that we have the simplified equation 10 * n = 30, our next goal is to isolate 'n'. Isolating a variable means getting it all by itself on one side of the equation. This gives us the direct value of the variable. In our case, we want to get 'n' alone on one side. To do this, we need to undo the multiplication that's happening between 10 and 'n'. The opposite of multiplication is division, so we'll divide both sides of the equation by 10. Why both sides? Because in math, we need to keep things balanced. Whatever we do to one side of the equation, we must do to the other side to maintain the equality. So, let's divide both sides by 10:
(10 * n) / 10 = 30 / 10
On the left side, the 10s cancel each other out, leaving us with just 'n'. On the right side, 30 divided by 10 is 3. So, our equation now looks like this:
n = 3
And there we have it! We've successfully isolated 'n' and found its value. Isolating variables is a fundamental technique in algebra and is used extensively in solving various types of equations. It's like peeling away the layers of an onion until you get to the core – the value of the variable.
The Verdict: n = 3
After carefully simplifying and solving the equation 2 * n * 5 = 30, we've arrived at the answer: n = 3. This means that if we replace 'n' with 3 in the original equation, the equation holds true. Let's double-check to make sure:
2 * 3 * 5 = 30
6 * 5 = 30
30 = 30
Yep, it checks out! So, we can confidently say that the value of 'n' that satisfies the equation is indeed 3. Finding the solution to an equation is like completing a puzzle, and in this case, we've successfully placed all the pieces in the right spots. It's a satisfying feeling to unravel the mystery and arrive at the correct answer.
