x +5 > 2x-9,        2x-11 > 4(x-1)

    -x > -14,          2x-11 > 4x - 4

     x < 14,              -2x  > 7

                                  x < fraction numerator negative 7 over denominator 2 end fraction

                              -3.5 > x

      Clearly, from the graph the solution is x < -3.5
