Getting comfortable with these types of real-world math applications can truly transform how you view challenges, both academic and in your daily life. It's all about translating a story into equations and then letting the math do its magic. So, let’s get ready to unlock the secrets of this intriguing car and motorcycle riddle!
Decoding the Puzzle: Understanding the Variables and What We Know
Alright, team, before we jump into any calculations, the most crucial first step in solving any word problem, especially one involving cars and motorcycles, is to really understand what the problem is telling us and what it's asking for. Think of it like being a detective gathering clues. We need to identify our knowns and our unknowns. In this specific puzzle, we have two types of vehicles: automobiles (cars) and motorcycles. We know a couple of key facts that will be our bread and butter for solving this. First off, we're told that the total number of vehicles in the lot is 52. This is a straightforward count of everything that has an engine and wheels. Secondly, and this is where it gets interesting, we're given the total number of wheels across all these vehicles, which is 130. Now, here's where common sense (and a little knowledge about vehicles) comes in: we know, without being explicitly told, that a standard car has 4 wheels, and a typical motorcycle has 2 wheels. These implied facts are just as important as the numbers given in the problem statement! The unknowns are what we're ultimately trying to find: the number of cars and the number of motorcycles. To make our lives easier and to move into the world of algebra, we'll assign variables to these unknowns. Let's use C to represent the number of cars and M to represent the number of motorcycles. Breaking down the problem this way helps us visualize the situation and prepares us to translate these facts into mathematical equations. It's all about clarity, guys! When you clearly define your variables and list out all the given information, you’ve already won half the battle against any tricky word problem. This systematic approach of information extraction is a foundational skill that will serve you well, far beyond just solving this car and motorcycle conundrum. So, remember: read carefully, identify the core components, and define your terms. That's how we set ourselves up for success!
Building Our Mathematical Bridge: Setting Up the Equations
Okay, now that we've expertly decoded our car and motorcycle riddle and clearly defined our variables (remember, C for cars and M for motorcycles), it's time for the really cool part: building our mathematical bridge. This is where we translate the everyday language of the problem into the precise language of algebra. We're going to create a system of linear equations, which basically means we'll have two (or more) equations working together to solve for our two unknowns. Don't let the fancy name scare you; it's quite intuitive when you break it down! Let's take our first piece of vital information: the total number of vehicles is 52. If C is the number of cars and M is the number of motorcycles, then simply adding them together should give us that total. So, our very first equation is super straightforward:
- C + M = 52 (This represents the total number of vehicles equation).
See? Easy peasy! Now, for our second piece of information: the total number of wheels is 130. This is where our knowledge about the number of wheels per vehicle comes into play. Each car (C) has 4 wheels, so the total number of wheels from cars would be 4C. Similarly, each motorcycle (M) has 2 wheels, so the total from motorcycles would be 2M. If we add the wheels from cars and the wheels from motorcycles, we should get our grand total of 130 wheels. Voila! Our second equation is:
- 4C + 2M = 130 (This is our total number of wheels equation).
And just like that, we've successfully set up our system of equations! We have two distinct pieces of information, and we've used each one to form an equation that relates our two unknowns, C and M. This is the heart of solving problems like this. It's a fundamental skill in algebra and something you'll encounter in many different contexts. Recognizing how to represent different aspects of a problem (like total items vs. total attributes per item) using separate equations is what truly empowers you to tackle more complex challenges. By carefully constructing these equations, we've laid a solid foundation for finding the exact number of cars and motorcycles in that lot. Next up, we'll show you how to solve this system and uncover the final answer. Get ready to put on your algebraic hat!
The Grand Reveal: Solving for Cars and Motorcycles
Alright, guys, this is the moment we've all been waiting for – the grand reveal! We've successfully set up our system of linear equations based on the total vehicles and total wheels in our parking lot:
- C + M = 52
- 4C + 2M = 130
Now, let’s solve this system to find the exact number of cars and motorcycles. There are a few ways to solve systems of equations, but for this one, the substitution method is super efficient and easy to follow. Here’s how we do it, step-by-step:
Step 1: Isolate a variable in one of the equations.
Let’s use Equation 1 because it's simpler. We can easily express M in terms of C (or C in terms of M, either works!):
M = 52 - C (This is our modified Equation 1)
Step 2: Substitute this expression into the other equation.
Now, wherever we see M in Equation 2, we’re going to replace it with (52 - C). This is the magic of substitution – it lets us reduce our problem from two variables to just one!
4C + 2(52 - C) = 130
Step 3: Simplify and solve for the remaining variable. Let's do the algebra carefully:
-
First, distribute the 2: 4C + (2 * 52) - (2 * C) = 130 4C + 104 - 2C = 130
-
Next, combine like terms (the
Cterms): (4C - 2C) + 104 = 130 2C + 104 = 130 -
Now, isolate the
2Cterm by subtracting 104 from both sides: 2C = 130 - 104 2C = 26 -
Finally, solve for
Cby dividing both sides by 2: C = 26 / 2 C = 13
Boom! We've found it! There are 13 cars in the parking lot. How cool is that?
Step 4: Substitute the value back into the isolated expression to find the other variable.
Now that we know C = 13, we can plug this value back into our M = 52 - C expression to find M:
M = 52 - 13 M = 39
And there you have it! There are 39 motorcycles in the lot. This step-by-step algebraic solution ensures we get accurate results every time. It's all about being methodical and precise.
Step 5: Verify your answer! This is a critical final step that many people skip, but it's super important to confirm your solution is correct. Let’s check both conditions:
- Total Vehicles: 13 cars + 39 motorcycles = 52 vehicles. (Matches the problem statement! ✅)
- Total Wheels: (13 cars * 4 wheels/car) + (39 motorcycles * 2 wheels/motorcycle) = 52 + 78 = 130 wheels. (Matches the problem statement! ✅)
Both conditions are met perfectly, which means our solution is spot on! So, the next time you're stuck in traffic, you can impress your friends by effortlessly calculating the number of cars and motorcycles based on wheels and vehicle counts. This systematic approach to finding the numbers is what makes math so powerful and satisfying!
