    x > 7

    Step-by-step explanation:

    Group the common factors, which are 3x and - 6x, so it looks like:

    3x - 6x + 12 < - 9

    -3x + 12 < - 9

    Subtract 12 from both sides:

    -3x < - 21

    Divide everything by - 3 to get your answer. Don't forget when dividing by a negative number, you have to flip the sign:

    x > 7
