I'm stuck on a nodal analysis problem. I'll post a picture of the problem as well as my attempt on it.
The problem:

My attempt:

In the picture on the link below I put vb = 0 and vc = vd in my equations and tried to solve vx but got the wrong answer. It should be -4 V.

So I don't know where I have gone wrong with this. Is there something wrong with my equations? Maybe vc isn't equal to vd? I really don't know, too confused. Would appreciate help with this.
