    Use the distributiver property which says

    a (b+c) = ab+ac

    so

    7 (9x-2) =

    (7 times 9x) + (7 times - 2) =

    (63x) + (-14) =

    63x-14

    If you would like to expand the expression 7 * (9 * x - 2), you can do this using the following steps:

    7 * (9 * x - 2) = 7 * 9 * x - 7 * 2 = 63 * x - 14

    The correct result would be 63 * x - 14.
