Question

1. TWO numbers total 72 and have a difference of 12 Find the two numbers

Answer 1

30 and 42 because when add to is equal to 72

Answer 2

Let the two numbers be x and y.

We know that:

x+y=72

x-y=12

Sum the two equations:

2x=84

Divide both sides by 2:

x=42

Plug this value for x in one of the two equations:

42-y=12 ---> y=42-12=30
