1. The problem statement, all variables and given/known data Solving for this circuit here, where V = -5V 2. Relevant equations 3. The attempt at a solution I found the equation for a summing op amp like this one, plugged everything in and ended up with -3V, which is marked wrong. I'm really at my wit's end here and the homework has been incorrect in the past so I'm not even sure this is the wrong answer, any help would be appreciated.
