Question

Find the solution to the system of equations.

8x – 4y = 16
8x + 4y = 16

x= ___
y= ___

PLS HELP

Answer 1

x =2, y =0

Explanation:

First we can add the equations to get rid of the y terms in each.

Adding them results in 16x = 32

Dividing by 16 gives us x=2

Substituting this back into equation 1 gives us 8(2) -4y =16

Simplifying,

16 - 4y =16

-4y = 0

y = 0
