How do I combine several hide and unhide statements

[JmundleBofA]

There is a series of questions and based on the answer the users selects, certain rows need to unhide or hide so the user can continue to answer more questions.

I think I need to use Case but I cannot make it work

Example:
If C10 = X then unhide rows 13-15
If C11 = X then Unhide rows 124-169
