Question

Solve the system
6x+2y=-4
x-2y=4

Answer 1

x = 0

y = -2

Explanation:

1. 6x+2y = -4

2. x - 2y = 4

in our second equation lets isolate x

x = 2y + 4

now lets plug this into our first equation

6(2y+4) + 2y = -4

12y + 24 + 2y =-4

14y +24 = -4

14y = -28

y = -2

lets plug in y into the second equation to find x

x = 2(-2)+4

x = -4+4

x = 0
