The Attempt at a Solution

Okay, I have all my work for both my superposition attempt and my nodal analysis attempt and the $$V_{o}$$ I found are not the same.

This leads me to believe I've made a mistake(if not several) in either my superposition attempt, nodal analysis attempt or both.

There is a typo on the first page of my nodal analysis attempt for i4 it says,

$$i_{4} = \frac{V_{B} - V_{3}}{3R}$$

when it should be,

$$i_{4} = \frac{V_{3} - V_{B}}{3R}$$

I used the correct i4 throughout all my calculations.

Any mistakes you find, tips/suggestions/comments are greatly appreciated.

Thanks again!
