Question

If the product of two number is 21 and the sum is 10 what are the two number.

Answer 1

The two numbers are 7 & 3

Answer 2

7 and 3

Explanation:

First, I listed factors of 21:

7 and 3

21 and 1

Then I added the factor pairs together to see which equaled 10:

7 + 3 = 10

10 is equal to 10

21 +1 = 22

22 is not equal to 10.
