Homework Equations
KCL, KVL, V = i R, super-node
The Attempt at a Solution
I added 5 currents and 2 KVL loops.

[tex]V_2\,=\,42\,V[/tex] <----- Right?
Now I do KVL loop 1
[tex](-12\,V)\,+\,(20\,V)\,+\,V_3\,=\,0\,\,\longrightarrow\,\,V_3\,=\,-8\,V[/tex]
And KVL at loop 2
[tex](-20\,V)\,+\,(10\,V)\,+\,(V_1\,-\,V_3)\,=\,0\,\,\longrightarrow\,\,V_1\,-\,V_3\,=\,10\,V[/tex]
[tex]V_1\,-\,(-8\,V)\,=\,10\,\,\longrightarrow\,\,V_1\,=\,2\,V[/tex]
Does that seem right?
