Question

THE SUM OF TWO NUMBERS IS 14 AND THEIR DIFFERENCE IS TWO

Answer 1

Answer:

Let first number = x

Let second number = y

x+y = 14

x-y = 2

Add the system of equations.

2x = 16

x= 8

Substitute into equation 1.

x+y=14

8+y=14

y=6

Check the solutions by using equation 2.

x-y=2

8-6=2

2=2

This checks out.
