    Lightbulb One more please, am I doing this right?

    I just want to make sure I am doing this correctly.

    2(x+1) -3(x-2)> 5

    2x + 2 - 3x + 6 > 5
    x + 2 + 6 > 5
    x + 8 > 5
    x > -8 + 5

    final answer is x > -3

    look at 2x-3x =/= x.

    that will change your answer, otherwise it "would" have been correct.

    So instead of being a -3 it should have been a possitive 3 making the final answer x < 3 Right???
