Solving for Three Numbers with Given Sums and Products

Algebraic equations are a fascinating aspect of mathematics, often involving the manipulation of variables to solve for unknowns. In this article, we will delve into a specific problem where we are tasked with finding three numbers whose sum is 24 and whose product is 126. This problem is a great example of how to approach and solve systems of equations in algebra.

Formulating the Equations

The problem can be broken down into two key equations. Let's denote the three unknown numbers as x, y, and z. We are given two conditions:

The sum of the three numbers is 24: (x y z 24). The product of the three numbers is 126: (x cdot y cdot z 126).

Using these equations, we can solve for x, y, and z. However, let's consider the integer solutions first, as they provide a clear and straightforward approach to the problem.

Integer Solutions

The integer solutions to these equations are x 14, y 9, and z 1. Let's verify these solutions:

Sum: (14 9 1 24). Product: (14 cdot 9 cdot 1 126).

We can see that these values satisfy both conditions of the problem, confirming that they are indeed the correct solutions. It's worth noting that x could be any non-zero value, but in the context of integer solutions, 14, 9, and 1 are the simplest and most practical choices.

Exploring Other Sets of Numbers

Let's consider another set of numbers where the sum is also 24 but the product is different. For example, the numbers 3, 2, and 1 have a sum of 24, but their product is 126. This provides us with an alternative set of numbers that also meet the criteria:

Sum: (3 2 1 6), but let's assume they are scaled up to match the original problem conditions. Product: (3 cdot 2 cdot 1 6), scaled up to 126.

To adjust for the original problem conditions, we can scale these numbers by a factor that maintains the required product. In this case, multiplying each by the factor necessary to achieve the product of 126 would lead us back to the same integers 14, 9, and 1.

Additional Considerations

While the integer solutions 14, 9, and 1 are the most straightforward, there are other sets of numbers that could satisfy the condition. For instance, if we consider the factors of 126, we find that 2, 3, and 7 are factors of 126. However, to sum up to 24, we need to scale these factors appropriately.

The factors of 126 are: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126. Considering the constraint of the sum being 24, we can derive that the numbers 7, 2, and 1 (when scaled appropriately) meet the condition:

Product: (7 cdot 2 cdot 1 14), scaled up to 126.

This demonstrates that there are multiple sets of numbers that can satisfy the given conditions, but the integer solution 14, 9, and 1 is the most intuitive and simplest to understand.

Conclusion

In conclusion, solving for three numbers with specific sum and product conditions involves setting up and solving systems of equations. The integer solutions 14, 9, and 1 are the most practical and straightforward, while other sets of numbers must be scaled appropriately to meet both conditions. This problem highlights the importance of algebraic reasoning and the application of integer solutions in solving real-world mathematical problems.
