Solve: Numbers Sum To 36, One Is Double The Other
Hey math enthusiasts! Ever stumbled upon a math problem that seems like a riddle wrapped in an equation? Today, we're diving into one of those intriguing puzzles. We've got a classic scenario: "The sum of two numbers is 36. If one of them is twice the other, what is the larger of these numbers?" Sounds like a brain-teaser, right? Well, don't worry, we're going to break it down step by step, making it super easy to understand. This isn't just about finding the answer; it's about understanding the process, the logic, and the 'aha!' moment when it all clicks into place. So, grab your thinking caps, and let's embark on this mathematical journey together! We'll explore how to translate word problems into algebraic expressions, a skill that's super useful not just in math class, but in everyday problem-solving too. Think of it as unlocking a secret code β the code of numbers! We'll look at the different ways we can approach this problem, from simple trial and error to more structured algebraic methods. And who knows? Maybe by the end of this article, you'll not only have the answer but also a newfound appreciation for the beauty and logic of mathematics. So, buckle up, and let's get started on this exciting quest to solve our number puzzle!
Understanding the Problem
Okay, let's dissect this problem like math detectives! The core of our mission is to figure out two numbers that add up to 36. That's our big picture. But there's a twist β these numbers aren't just any two random numbers. There's a special relationship between them: one of the numbers is exactly twice the size of the other. This is crucial information, guys! It's like a secret ingredient that we need to make our math recipe work. Now, the ultimate question we're trying to answer is: What's the bigger of these two mystery numbers? This is the treasure we're hunting for. To get there, we need to translate this word problem into a language that math understands β algebra! Think of it like translating a sentence from English to Spanish. We need to convert words into mathematical symbols and equations. This is where variables come into play. A variable is like a placeholder, a symbol (usually a letter like x or y) that represents an unknown number. In our case, we have two unknowns, but luckily, their relationship is defined. This makes our job a little easier. We can represent the smaller number as 'x' and the larger one (which is twice the smaller) as '2x'. See how we're already starting to build our mathematical framework? Next, we'll use the information about the sum to create an equation. This equation will be our roadmap to finding the value of 'x', and once we have 'x', we can easily find both numbers and, most importantly, identify the larger one. So, stay tuned as we transform this puzzle into a solvable equation!
Setting Up the Equation
Alright, let's get down to the nitty-gritty and translate our word problem into a proper mathematical equation. This is where the magic happens, guys! Remember, we've identified our two mystery numbers: the smaller one we're calling 'x', and the larger one, which is twice the smaller, we're calling '2x'. Now, here's the golden nugget of information: these two numbers, when added together, make 36. This translates directly into an equation. We simply add 'x' and '2x' and set the sum equal to 36. So, our equation looks like this: x + 2x = 36. See how neatly we've transformed the words into symbols? This is the power of algebra! Now, we have a clear, concise mathematical statement that we can work with. But we're not done yet. The next step is to simplify this equation. Look closely β we have two terms on the left side that both involve 'x'. These are called 'like terms', and we can combine them. It's like having one apple (x) and adding two more apples (2x). How many apples do you have? Three! So, x + 2x simplifies to 3x. Our equation now looks even cleaner: 3x = 36. We're getting closer to cracking the code! This simplified equation is much easier to solve. It tells us that three times our mystery number 'x' equals 36. To find 'x', we need to isolate it on one side of the equation. This involves using the concept of inverse operations. Think of it like undoing a knot β we need to perform the opposite operation to untangle 'x'. So, let's move on to the next step and solve for 'x'.
Solving for 'x'
Okay, guys, we've arrived at the exciting part where we unravel the mystery of 'x'. We've got our simplified equation: 3x = 36. This equation is telling us that three times our unknown number 'x' is equal to 36. To find the value of 'x', we need to get it all by itself on one side of the equation. This is where the concept of inverse operations comes into play. Remember, in mathematics, we can perform the same operation on both sides of an equation without changing its balance. It's like a seesaw β if you add or subtract the same weight from both sides, it stays level. In our case, 'x' is being multiplied by 3. The inverse operation of multiplication is division. So, to isolate 'x', we need to divide both sides of the equation by 3. This gives us: (3x) / 3 = 36 / 3. On the left side, the 3 in the numerator and the 3 in the denominator cancel each other out, leaving us with just 'x'. On the right side, 36 divided by 3 is 12. So, our equation now reads: x = 12. Eureka! We've found the value of 'x'! This means that the smaller of our two numbers is 12. But hold on, we're not quite at the finish line yet. Remember, the question asks for the larger of the two numbers. We know that the larger number is twice the smaller number, which we represented as '2x'. Now that we know 'x', we can easily find '2x'. We simply multiply our value of 'x' (which is 12) by 2. So, 2x = 2 * 12. Let's do that calculation in the next section to find our final answer!
Finding the Larger Number
Alright, math detectives, we're in the home stretch! We've successfully cracked the code for 'x', discovering that the smaller number is 12. But remember our quest? We're on the hunt for the larger number. Now, the problem told us that the larger number is twice the smaller number. In mathematical terms, we represented this as '2x'. So, to find the larger number, we simply need to substitute the value we found for 'x' (which is 12) into the expression '2x'. This means we're calculating 2 times 12. Let's do the math: 2 * 12 = 24. Ta-da! The larger number is 24. We've found our treasure! But before we declare victory, let's just take a moment to make sure our answer makes sense in the context of the original problem. We know that the two numbers should add up to 36. We found the smaller number to be 12 and the larger number to be 24. Let's add them together: 12 + 24 = 36. Awesome! It checks out. Our numbers fit the first condition. We also know that the larger number should be twice the smaller number. Is 24 twice 12? Yes, it is! So, our numbers also satisfy the second condition. This gives us confidence that we've solved the problem correctly. The larger of the two numbers is indeed 24. We've not only found the answer but also verified it, which is always a good practice in mathematics. So, let's wrap up our mathematical journey and celebrate our successful problem-solving adventure!
