7(a - 2ab + 2) - 8a + (-15) + 11ab


= 7a - 14 ab + 14 - 8a - 15 + 11 ab


= (7a - 8a) + (-14ab + 11ab) + (14 - 15)


= -a - 3ab - 1

First you want the remove the parentheses from he equation:
7(a - 2ab + 2) - 8a + (-15) + 11ab
7a - 14ab + 14 - 8a -15 + 11ab

Now you want to add or subtract like terms
7a - 14ab + 14 - 8a -15 + 11ab
(7a - 8a) (-14ab +11ab) (14-15)
-1a-3ab-1

If you want you can have an answer of either:
-1a-3ab-1 or -a-3ab-1
