Q$1.$

What are the values of$$V$1$and V$4?$Using plus references at $$the top of $$the vertical branches and at $$the left horizontal branches, what are the seven branch voltages in $$terms of $$node voltages?

Q$2!$

Set up $$the node equations for the circuit, and solve for V$2$and V$3,$using nominal values of $$resistances and nominal values of $$voltage sources.
