Question

The sum of two numbers is 8. Their difference is 24. What are the two numbers ? Write a system of linear equations and solve using the elimination method.

Answer 1

x=16

Explanation:

let:

> x be one number

> y be the other number

system of Equations:

> x+y=8

> x-y=24

Using elimination method the y's cancel each other out, and we are left with

2x = 32

divide by 2 on both sides to get x by itself

AND

x=16
