Thank you for the opportunity to help you with your question!

f(g(x))=6(6x)                                                                       f(g(x))=2(x+7/2)-7

=36x                                                                                              =x+7-7

g(f(x))=6(6x)                                                                                  =x

=36x                                                                                     g(f)=(2x-7+7)/2

f and g are inverses of each other                                                =x

                                                                                                  f and g are inverses of each other 

Please let me know if you need any clarification. I'm always happy to answer your questions.
