The sum of two numbers is 56 and the difference is 12 . What are the numbers?

Answer 1

x+y =56

x-y = 12

add to get

2x = 68

divide by 2

x = 68/2 = 34

y=56-34= 22

the numbers are 22 and 34

Answer 2

Start out with two variables.

x = 1st number

y = 2nd number

form two equations with those variables

x + y = 56

x - y = 12

add the variables together

2x = 68

solve for x

x = 34

now solve for y using x.

y = 56 - 34

y = 22
