3x-y=-4

2x-y=0

-3x+y=4

-x=4

x=-4

Plug that back into either equation to solve for y.

Second equation:

2x-y=0, 2x=y, y=2x

Firs equation:3x-y=-4

3x-y=3x-2x= x=-4 x=-4

y=2x=2*(-4)=-8 y=-8

Check of result:

First equation:

3x-y=3*(-4)-(-8)=-12+8=-4

Second equation:

2x-y=2*(-4)-(-8)=-8+8=0
