What is the Correct Setup for a Supernode in a Circuit?

[th3plan]

Ok i have a problem with the supernode. So this is what i done so far

V3-v1=10

now for supernod equation, this is where idk if I am correct

v1/4+ (v1-v2)/2+(v2+v3)/2+(v3/8) = 0


Is this setup right ?

Where do i go from here ?

There's supposed to be an accompanying picture of the circuit, right? You forgot to include that.

I really can't read the value of the current source in the circuit diagram. Could you enlarge the picture?
