Electric Circuits problem - Superposition

[Victor Feitosa]

Homework Statement

The problemas statement is:
"Find Vo and Io by the superposition principle"

Homework Equations

Nodal Analysis and The Superposition Theorem.

The Attempt at a Solution

So, I tried to shutdown first the independent 30V tension font. It led me to Vo = 8V.
Then, turning off the 6A current font, led me to Vo = 2V.
So the final Vo will be equation the sum of the two others: 10V.

The correct anwser is 17,99V(so, Io = 1,799A).
Thank you!

You'll have to show some more details about your attempt, particularly the part concerning the 6 A source operating alone (that is, when the 30 V source is suppressed). Show your work.
