  x - 3y = 1   ⇒ 3x - 9y = 3
3x - 5y = 11 ⇒ 3x + 5y = 11
                             -14y = -8
                              -14    -14
                                   y = ⁴/₇
                            x - 3y = 1
                           ⁴/₇ - 3y = 1
                         - ⁴/₇        - ⁴/₇
                                -3y = ³/₇
                                 -3     -3
                                   y = ⁻¹/₇
                             (x, y) = (⁴/₇, ⁻¹/₇)
