-4x -2y = 12
-x + 4y = 12
Multiply the first equation 2 then add to the second equation.
-8x -4y = 24
-x + 4y = 12
___________
-9x = 36
Divide both sides by-9
x = -4
Plug -4 back into either original equations and solve for y.
- -4 + 4y = 12
4 + 4y = 12
Subtract 4 from both sides
4y = 8
Divide both sides by 4
y = 2
(-4,2)
