Hey math whizzes! Ever get stuck trying to solve an equation and wonder if you're even doing it right? Today, we're diving into a classic problem involving the addition property of equality and seeing how two students, Cora and Mitul, tackle it. It’s all about making those equations work for you, not against you! We'll break down their steps and figure out who’s on the right track to cracking the code of 14xβˆ’29=24βˆ’21x14 x-29=24-21 x. So grab your calculators, maybe a snack, and let's get this math party started!

The Challenge: Solving 14xβˆ’29=24βˆ’21x14x - 29 = 24 - 21x

Alright guys, let's set the stage. We've got this equation: 14xβˆ’29=24βˆ’21x14 x-29=24-21 x. Our mission, should we choose to accept it (and we totally should!), is to find the value of xx that makes both sides of this equation equal. Think of an equation like a perfectly balanced scale. Whatever you do to one side, you have to do to the other to keep it balanced. That's where our trusty addition property of equality comes into play. This property is super important because it lets us add the same number to both sides of an equation without changing the solution. It's a fundamental rule in algebra, and mastering it is key to solving more complex problems down the line. Without a solid understanding of this property, you'll find yourself making common mistakes that can lead you down a rabbit hole of incorrect answers. So, pay attention, because understanding this isn't just about getting this one problem right; it's about building a strong foundation for all your future algebraic endeavors. We're going to dissect Cora's and Mitul's approaches, looking closely at their very first steps. Did they correctly use the addition property? Let's find out!

Cora's Approach: A Bold First Move

Cora starts with 14xβˆ’29=24βˆ’21x14 x-29=24-21 x. Her first step is to rewrite it as 35xβˆ’29=2435 x-29=24. Now, let's rewind and analyze. To get from the original equation to her new one, Cora seems to have added 21x21x to both sides of the equation. Let's check: (14xβˆ’29)+21x=(24βˆ’21x)+21x(14x - 29) + 21x = (24 - 21x) + 21x. On the left side, we combine the xx terms: 14x+21xβˆ’29=35xβˆ’2914x + 21x - 29 = 35x - 29. On the right side, the βˆ’21x-21x and +21x+21x cancel each other out, leaving us with just 2424. So, her rewritten equation 35xβˆ’29=2435x - 29 = 24 is a perfectly valid result of applying the addition property of equality by adding 21x21x to both sides. This is a great strategy because it groups all the xx terms on one side, making it easier to isolate xx later. It shows she understands that adding the same value to both sides maintains the equation's balance. This initial step is crucial because it simplifies the equation, moving us closer to the solution. Many students find it easier to work with equations where all the variable terms are on one side and the constant terms are on the other. Cora's move effectively starts this process. By consolidating the xx terms, she's setting herself up for the next steps, which will likely involve isolating the xx variable. This demonstrates a clear understanding of algebraic manipulation and the fundamental properties that govern them. It's not just about moving numbers around; it's about strategically simplifying the problem into a more manageable form. Her confidence in applying this property suggests a good grasp of algebraic principles, a trait common among successful math students. She's not afraid to make a move that drastically changes the appearance of the equation, as long as she knows it's mathematically sound. This kind of proactive problem-solving is what separates good students from great ones.

Mitul's Strategy: Focusing on Constants

Now, let's look at Mitul. He starts with the same equation: 14xβˆ’29=24βˆ’21x14 x-29=24-21 x. His first step is to rewrite it as 14x=53βˆ’21x14 x=53-21 x. How did he get there? It looks like Mitul added 2929 to both sides of the original equation. Let's test this: (14xβˆ’29)+29=(24βˆ’21x)+29(14x - 29) + 29 = (24 - 21x) + 29. On the left side, the βˆ’29-29 and +29+29 cancel out, leaving us with 14x14x. On the right side, we combine the constant terms: 24+29βˆ’21x=53βˆ’21x24 + 29 - 21x = 53 - 21x. So, Mitul's rewritten equation 14x=53βˆ’21x14x = 53 - 21x is also a correct application of the addition property of equality. He chose to add 2929 to both sides. This strategy also aims to simplify the equation, but in a different way than Cora's. Mitul's move isolates the 14x14x term on the left side. This is another valid and effective way to begin solving the equation. By moving the constant term from the left side to the right, he's again working towards getting the equation into a simpler form. This also demonstrates a solid understanding of the addition property. Mitul's choice might seem less dramatic than Cora's, but it's equally important. Sometimes, the best strategy is the one that makes the most straightforward move first. His approach is methodical, focusing on eliminating constants first. This can be particularly helpful for students who prefer a step-by-step process, systematically clearing terms from one side before tackling the others. His ability to correctly apply the addition property here shows that he's not confused by the presence of negative terms or multiple variable terms. He correctly identified that adding 29 to both sides would cancel out the -29 on the left and combine the constants on the right. This precision in applying the property is commendable and essential for accurate algebraic solutions. His move is strategic and sound, setting him up for the subsequent steps needed to solve for xx.

Applying the Addition Property Correctly: The Verdict

So, the big question: Who is correctly applying the addition property of equality? The answer, my friends, is both Cora and Mitul! They both used the addition property correctly, just in slightly different ways. Cora chose to add 21x21x to both sides to consolidate her variable terms, resulting in 35xβˆ’29=2435x - 29 = 24. Mitul chose to add 2929 to both sides to isolate his 14x14x term, resulting in 14x=53βˆ’21x14x = 53 - 21x. Both of these steps are perfectly valid applications of the addition property of equality. The beauty of algebra is that there often isn't just one
