I'd show what work I have done, but I don't even know what my objective is. I am prompted to enter a value for x in the answer box.

your answer will be in terms of a,b,c, and d
just multiply both sides by cx+d and then just simplify

edited out my answer - you have to do it yourself.
get rid of denominator. Get all terms with x on one side of the equation, them extract the x.

Alright, but I'm not sure what I am trying to do here. Am I just trying to isolate x? Where does the 9 even play in?

When the problem is stated as "solve ... for x", the desired answer is of the form
x = ...
and you get there by manipulating the equation using the rules of algebra, such as:
you can add, subtract, multiply, or divide as long as you do the same thing on both sides of the equals sign, thus maintaining the equality
you can multiply or divide both the numerator and denominator of a fraction by the same thing...that is, multiply the fraction by 1.
For
you should start by multiplying both sides of the equation by (cx + d)
It creates a wight of extraordinary magical power.
