Question

The sum of two positive integers is 13. The difference between these numbers is 7. What is their product?

Answer 1

Answer:

30

Step-by-step explanation:

set the two values with variables x and y

x+y = 13

x-y = 7

adding both equations we get

2x = 20

therefore x = 10 and y = 3

xy = 10*3 = 30
