I try using nodal analysis but don't know how to treat the voltage sources going into the nodes. So i decided to use mesh analysis and found all Ia, Ib, Ic, and Id.. I got Vo= .3 V but I'm not sure if this is right.. And also I have no idea how you're supposed to approach it using nodal analysis either.

Firstly can someone verify that the answer is .3 V? Cuz I got the current Ic going through that 1k resistor on the right (which is Vo) is .3 mA , therefore .3*1= .3 V..

And secondly can someone help me on how I can start this problem using nodal analysis?

I would REALLY appreciate it. Thanks a lot!
