## Homework Statement

Am having trouble solving the initial part of this problem, I think I am being confused by the dual voltage sources.

2. Homework Equations

2. Homework Equations

I=V/R ΣI at a node =0

## The Attempt at a Solution

V3/R3 - (V1/R1+V2/R2) = 0

V3=12-VA

V1=4-VA

V2=VA-4

However this must be incorrect somewhere as It is impossible to isolate Va from the above equations. Am normally very strong mathematically but find basic electronics very confusing for some reason!
