## Homework Statement

I have to use Nodal analysis to find Vx

## Homework Equations

our prof said that if we want to find the number of unknowns and eqxns necessary then we need to find all the nodes in circuit - the reference node - number of voltage sources, for this circuit that would be 4 nodes - 1 ref - 3 vsrc = 0 this doesn't make sense in this circuit

## The Attempt at a Solution

my attempt at this problem I'm pretty sure its not right, here is what i did:

KCL @ node b: -(Vx/20k) + (Vx/30k) + (Vx-20)/10k = 0 solving for Vx

I get that Vx = 24V. I got the eqxn above by subtracting the two voltages on the leftmost node and adding the voltages on the rightmost node and then doing the KCL. I'm pretty sure its not right so please help
