5x - 14y = 22 ⇒   5x - 14y = 22
-6x + 7y =  3  ⇒ <u>12x - 14y = -6</u>
                                    <u>-7x</u> = <u>28</u>
                                     -7     -7
                                       x = -4
                            5x - 14y = 22
                         5(-4) - 14y = 22
                           -20 - 14y = 22
                         <u>+ 20           + 20</u>
                                  <u>-14y</u> = <u>42</u>
                                  -14    -14
                                       y = -3
                                  (x, y) = (-4, -3)
