To simply to expression 6ab+3ab-7ab, we do:
6ab+3ab-7ab+= (Just do regular addition and subtraction if they have the same coefficent)
9ab-7ab=
2ab
So the answer is C.

Simplifying 6ab + 3ab - 7ab
so we can write it
6ab + 3ab - 7ab = 0 ( because there is nothing on right side )
9ab - 7ab = 0
2ab = 0
So the coefficient of
ab
is
2.
Correct option is C.
