The Attempt at a Solution

I found the partial voltages v1 & v2 due to the 2A current source(shutting off the indep. voltage source), but i can't get the partial voltages due to the 3V voltage source(shutting of the indep. current source) can someone help!

You open the current source, not shunt it. Shunt the voltage source.

I already solved the partial voltages due to the 2A sourcei did that by shutting off the voltage source!I only need to find the other partial voltages due to the 3V source by shutting off the 2A source.What I am asking is how to find V1 and V2 if the circuit looked like this:

Ive tried mesh and nodal analysis but i keep getting the wrong answer.

Your figure is wrong. Read wildman's post.
