The problem almost begs you to set up a system of 2 equations.The sum of two positive numbers is 42 and their product is 425. What are the two numbers.

If you had reason to think the numbers might be integers, you could just look at factor pairs for 425 and see if any of them worked. They are 1*425, 5*85, 17*25. One of those has the right sum, so you have the answer.The sum of two positive numbers is 42 and their product is 425. What are the two numbers.

But the other suggested methods take less guessing, and will work even if the numbers are not integers.
