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:



thanks in advance!

 

I see that I made a mistake with the input voltage (the left side) which ofc. should say V(index)i not and Vo.

 

Yes, the circuit is a difference amp.

 

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

 

great! thank you.
