    Inequality.

    I have an inequality.


    3 - 3(x-2) > 0

    So i am quite unsure about how to do these we have only covered them once so please let me know if/when I go wrong.

    3 - 3x +6 > 0
    Move 6 over.

    3 - 3x >6

    Move 3 over.

    3x > 9

    x > 3


    ??? Hows that?

    Not quite. You've got some sign issues

    3-3(x-2)>0

    3-3x+6>0

    3-3x>-6

    -3x>-9

    x<3
