-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)
