    2/3 (3x + 9) = - 2 (2x + 6)

    Step by step

    2/3 * 3x and 2/3 * 9 = 2x and 6

    which is 2x + 6 (since 6 is a positive put a plus 6 [ + 6 ])

    -2 * 2x and - 2 * 6 = - 4x and - 12

    which is - 4x - 12 (since 12 is negative put a minus 12 [ - 12 ])

    We now have 2x + 6 = - 4x - 12

    now add 4x on both sides

    2x + 6 + 4x = - 4x - 12 + 4x

    6x + 6 = - 12

    now Subtract 6 from both sides.

    6x + 6 - 6 = - 12-6

    6x=-18

    finally Divide both sides by 6.

    6x/6 = - 18/6

    x = - 3

    The answer is x=-3
