## Homework Statement

Find V1,V2,V3,I1,I2,I3

## Homework Equations

## The Attempt at a Solution

Analysis at super node:

V3-V1=40 (equation 1)

(V1/40)+(V1-V2/40)+(V3-V2/20)=0

2V1 - 3V2 +2V3 = 0

After substituting in equation 1:

4V1-3V2 = -80

Analysis at V2

(V1-V1/40)+(V2/20)+(V2-V3/20)=0

After substituting in equation 1:

-3V1+5V2 = 80

But I think I'm doing something wrong, I don't feel like the voltages should be zero...
