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.
