a.) f(x) = 7x-3

b.)f(x) = 2/3 x+2 (there were no brackets the x+2 is just beside the fraction)

Rule: If f(g(x)) = x and f(f(x)) = x, then f(x) and g(x) are inverse of each other.

This is my exercise question I dont understand what to do I get the rule but how am getting an answer of x? I have the solutions also, but I dont know what to do with the numbers am I solving for something? :uhh:
