Question

The sum of two numbers is 14 and their diffrence is 2

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
