-4x + 7y = 9  ⇒ -4x + 7y = 9  ⇒     8x - 14y = -18
2y = -5x - 22 ⇒ -5x - 2y = 22 ⇒ -35x - 14y = 154
                                                               43x = -172

                                                     -4(-4) + 7y = 9
                                                          16 + 7y = 9
