    Will I get any Marks for This naxmax9

    JC HL Question

    -17<1-3x<13 final answer -4 and 6

    my workings

    - 1-3 = -2

    -17 + 13 = -4

    - -2-4 = 6

    Final answers -4 and 6?

    Just wondering or should I learn the example from study clix?

      3x < 1 + 17

      3x < 18

      x < 6

      1 - 3x < 13

      1 - 13 < 3x

      -12 < 3x

      -4 < x

      This is how it should be laid out but as long as you got the same answers, you should for certain get marks.
