It is pretty much guaranteed to come up in the exam, just with different values... hopefully easier than this example.

I guess you better learn it then.

Good thing by using LaTeX you can type all your work.

http://en.wikipedia.org/wiki/Superposition_theorem

I don't have a formal education in electronics, and so I've never had to solve something like this (Heck, I've never even heard of that theorem until now).
But I'll share my answers (which I don't know are correct) if you share yours.
It's justified because neither of us are 100% sure.

What do you mean "taking the reading at 3V"?

Both problems can be solved by inspection in your head performing onlly the following arithmetic compuations (some more than once) between the two problems:

3+9, 5+5, 25+1, 5*5, 5*6, 3/1, 10/2, 15/3.
