Warned, no template, no effort
I have no idea how to do the node analysis for this circuit. I have done the mesh analysis and got the current in R3 to be 4A is this right?

I know that there are two exceptional nodes at the center and at the first the voltage is 2v and the voltage drop across R4 is 60v

So
Node 1: (V2-10)/3=5
Node 2: ((V2-10)/3)-(V2/4)+((V2-V3)/10)
Node 3 (V3-V2)/10=-6

This question doesn't look right to me. Shouldn't the current flow toward the bottom right? Let's see what others think but I think this question is suspect.

I have solved it now. I just ignored the first node solved the second and third and got 4 A.
