    Hey, I'm kinda stuck on a rather trivial problem and I need some help. My main problem is whether this would qualify as a "difference amplifier"? Because if it does then I think (correct me if Im wrong) the answer would be obtained by the use of superposition.

    The problem is:

    Yes, the circuit is a difference amp.

    It is a difference amplifier, and superposition is the easiest way to solve the problem.
