Homework Statement
Find Vx given:
R1 = 6kW; R2 = 6kW;
R3 = 2kW; R4 = 3kW;
VS = 5V; IS = 5mA
Relevant Equations
V=IR
Hello.
Can someone give m e pointers on how to find the value of vx given that it is inside a supernode(will it be the valueof the voltage inside or the difference of potential between the two nodes?): here's the exercise and what I've done so far attached.
Your time and attention are deeply appreciated.
Thank You.

I think you forgot to attach your work?
Anyway, you'll want to use Kirchhoff's laws to make a set of equations to solve.
Khan Academy has some good tutorials on this subject.

I'm missing something. What does the "m" stand for in this case?

OK, so you've got everything you need to write equations using Kirchoff, just as @DaveE said.

You HAVE to show some work before we can be any more help
