If 9(x-9) = -11 then x = ?
I thought I could just distribute it but the answers are in fraction form. I'm not sure how to find the fraction unless I just substitute the answers in a calculator.
It's not a homework question, it's from an ACT prep book.

Distribute the 9 to what is inside the parantheses.
I'll get you started.
$$\large 9(x-9) = -11$$
$$\large 9x - 81 = -11$$
