How do I simplify this? I got to 2/(3/x)-1 but I don't know how to simplify that further. Please show steps.

(f o g) (x) means that we substitute 3/x into x for f(x)
2 / ((3/x) - 1)
We have to get rid of the fraction in the denominator. Multiply both the top and bottom by x
(f o g) (x) = [tex]\frac{2x}{3 - x}[/tex]. This is as simplified as it can get.
