The problem was assigned in my Structural Analysis class, and I am having some difficulty with it.

My professor said the problem is "very easy" if we just think about what the fixed end moment on a cantilever is. However, I don't see how this is relevant considering the member ACE is not a cantilever...

The only other way I see to do this is using the moment distribution method, but I'm uncertain as to what happens with the internal hinges; we've never had a problem like this in class, and there is no relevant example in my textbook. Any suggestions?

Remember that hinges cannot transfer moment - only shear. Try drawing three separate free body diagrams (member ACD, member DE, and member EFG) knowing that the only reactions at the ends of member DE can be shear.

The free body diagram that you come up with for ACD should look much more manageable than the initial problem - a end loaded cantilever with redundant roller support.
