        -6(4x + 1) + 7x + 9(x - 3) = 4
-6(4x) - 6(1) + 7x + 9(x) - 9(3) = 4
         -24x - 6 + 7x + 9x - 27 = 4
        -24x + 7x + 9x - 6 + 27 = 4
                                -8x + 21 = 4
                                       - 21 - 21
                                        -8x = -17
                                         -8     -8
                                            x = 2.125
