1x + 4y = 4 ⇒ 6x + 24y = 24
6x -  8y = 0 ⇒ 6x -   8y = 0   
                               32y = 24
                                32     32
                                   y = 3/4
                     x + 4(3/4) = 4
                            x + 3 = 4
                                -3   -3
                                 x = 1
                            (x, y) = (1, 3/4)
