    The correct answer is x = 8

    Step-by-step explanation:

    12x > 9 (2x-3) - 21

    First start with parenthesis

    12x > 18x - 27 - 21

    -27-21 = - 48

    12x > 18x - 48

    Now move the x value to the opposite side and switch the sign

    12x - 18x > - 48

    Combine like terms

    -6x > - 48

    Divide - 48 by 6

    x = 8
