7v-10 given that -9v-9=9 simplify the answer. I do not understand the question, can someone help pls.

I believe the question should read:

Evaluate 7v-10 given that -9v-9=9 simplify the answer.

-9v-9=9
and solve for v.
Substitute the (numerical) value of v into 7v-10 to get the answer required.

-6(9-9v)
