The choices are:
A. -2
B. 7/2
C-4/7
D.7/4

Can somebody show me the step by step procedure how to solve this type of problem:
Any help would be appreciated..
In this case, it is unclear whether you are still in the process of doing the exam, or if this is a question you encountered in an exam you have now FINISHED that you could not do. If it is the former, it's against the policy of MHF to do work for a student that constitutes part of their final grade. If it is the latter though, we can help you.
