## Homework Statement

Use nodal analysis to find ##V_o##.

## Homework Equations

##\sum I = 0##

##I = V/R##

## The Attempt at a Solution

So the book started throwing voltage sources into nodal analysis and I'm a bit unsure about this problem. The answer is listed as ##V_o = 3.89 V##.

All they have taught so far is to apply KCL to find the node voltages. Also, if a voltage source is connected between ground and a node, then the voltage at that node is equal to the voltage of the source.

This leads me to an important question about the problem at hand. I believe ground is located directly beneath the ##12 V## independent voltage. So couldn't I say directly above the voltage source and below the resistor is some ##V_x = 12 V##?

Finding the voltage ##V_2## across the middle branch has proven to be troublesome.
