  3x + 2y = 12                              5x - 2y = 4  -3x           -3x                             -5x          -5x 2y = 12 - 3x                                      -2y = 4 - 5x divide by 2 on both sides            divide by -2 on both sides y = 6 - 3/2x                                        y = -2 + 5/2x
