Homework Statement
Find the output voltage. a picture is attached giving all information.
The Attempt at a Solution
I'm new to op-amps, and I wasn't sure how to go about solving this. I thought it looked like an inverting op-amp but I wasn't sure. Since I wasn't sure, I tried to use superposition on V1, V2, and V3 to get the Vout. When I did this (my work is attached), I started with V1 and grounded out V2 and V3. I still wasn't sure on what to do from there so I tried to make an equivalent circuit to help but it ended up confusing me more as it looked like Vout = 0V.
I need some pointers, and if someone could give me a "plan" on what to do if I get a problem like this where I'm not sure what type of op-amp it is, I'd appreciate it.
