Question

Use the elimination method to solve the system of equations. Choose the correct ordered pair. 

4x + 8y = 16
4x - 8y = 0

Answer 1

4x + 8y = 16
4x - 8y = 0
-----------------add
8x = 16
x = 16/8
x = 2

4x + 8y = 16
4(2) + 8y = 16
8 + 8y = 16
8y = 16 - 8
8y = 8
y = 8/8
y = 1

solution is (2,1)

Answer 2

c (2,1) it is this add both equations it will give you this
