-4x-2y=4
2y=-4x-4
I need to find the solution to this equation, please help?

-4x - 2y = 4 ⇒ 2y = -4x - 4
2y = -4x - 4 ⇒ 2y = -4x - 4
                        4y = 8x - 8
                         4         4
                          y = 2x - 2
               2(2x - 2) = -4x - 4
                   4x - 4 = -4x - 4
                 +4x        +4x       
                   8x - 4 = -4
                        +4   +4
                          8x = 0
                           8     8
                            x = 0
               -4(0) - 2y = 4
                        -2y = 4
                         -2    -2
                           y = -2
           -4(0) - 2(-2) = 4
                           4 = 4
                     (x, y) = (0, -2)
