Understanding the Equation
The equation R + 14 = 39 represents a simple yet crucial concept in algebra. It states that when the value of R is added to 14, the result equals 39. Our primary goal is to isolate R on one side of the equation to determine its specific value. This involves employing algebraic techniques that maintain the equation's balance while simplifying it. To effectively solve this, we need to understand the role of inverse operations, which essentially undo each other. For instance, addition and subtraction are inverse operations, as are multiplication and division. Utilizing these inverse operations is key to isolating the variable and finding its value. The equation R + 14 = 39 serves as a stepping stone to understanding more complex algebraic equations, making it an essential concept for students and anyone interested in mathematics. By mastering the methods to solve such equations, we build a strong foundation for tackling more advanced mathematical problems.
Solving for R: A Step-by-Step Approach
To solve for R in the equation R + 14 = 39, we need to isolate R on one side of the equation. This can be achieved by using the principle of inverse operations. Since 14 is being added to R, we can subtract 14 from both sides of the equation to maintain balance and isolate R. This process is crucial in algebra as it ensures that the equality of the equation remains intact. Let's break down the steps:
- Start with the equation: R + 14 = 39
- Subtract 14 from both sides: R + 14 - 14 = 39 - 14
- Simplify: R = 25
Therefore, the value of R that satisfies the equation is 25. This methodical approach not only provides the solution but also reinforces the understanding of algebraic manipulation. By following these steps, we've successfully determined the value of R, which is a cornerstone in solving various algebraic problems. The beauty of this method lies in its simplicity and effectiveness, making it a fundamental tool in the world of mathematics.
Verifying the Solution
After finding a solution, it's always a good practice to verify its correctness. This step ensures that the value we found for R indeed satisfies the original equation. To verify, we substitute the value of R (which we found to be 25) back into the original equation R + 14 = 39. If the left-hand side of the equation equals the right-hand side after substitution, then our solution is correct. Let's perform the verification:
- Original equation: R + 14 = 39
- Substitute R = 25: 25 + 14 = 39
- Simplify: 39 = 39
Since the left-hand side (39) is equal to the right-hand side (39), our solution R = 25 is correct. Verification is a critical step in mathematical problem-solving, as it helps to avoid errors and builds confidence in the solution. By verifying, we confirm that our understanding of the equation and the steps we took to solve it are accurate. This practice is invaluable in mathematics and enhances our ability to solve more complex problems with assurance.
Analyzing the Answer Choices
In the given question, we have several answer choices: A) 53, B) 25, C) 24, and D) 546. We have already determined that the correct value of R is 25. Now, let's analyze each option to understand why some are incorrect and reinforce why our answer is the right one. This process not only confirms our solution but also helps in understanding common mistakes that can be made while solving such equations. Understanding why certain options are incorrect is as important as knowing why the correct answer is right.
- A) 53: This answer is incorrect because it likely results from adding 14 and 39 instead of subtracting. This highlights a common mistake where the operation is misunderstood.
- B) 25: This is the correct answer, as we have demonstrated through our step-by-step solution and verification.
- C) 24: This option is close to the correct answer but is incorrect. It might arise from a simple calculation error or a misunderstanding of the subtraction process.
- D) 546: This answer is significantly larger than the expected value and is clearly incorrect. It likely comes from a major misunderstanding of the problem or a significant calculation error.
By analyzing these options, we gain a deeper understanding of the problem-solving process and the importance of careful calculation and conceptual understanding. This approach is crucial in mathematics, as it helps in developing problem-solving skills that go beyond just finding the answer.
