Using superpostion to find voltage

[duffman1278]

I cannot seem to figure out how to start this problem when I eliminate the 12V source.

I don't seem to see any resistors that are in parrallel or series. I'm just completely blank on this.

Hopefully someone can put me in the right direction for this problem already.

This looks like a homework problem.

Do you know how to write mesh equations?
