Solving for this circuit here, where V = -5V

Homework Equations

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.

I think you must have a math error somewhere. Are all the signs correct?

I think so, I ended up writing it out and still got 3V

Can you post it?
