SUMMARY
The discussion focuses on calculating the voltage Vx in an electrical circuit using superposition and Kirchhoff's Laws. The final calculated value of Vx is 9.818181V, but a correction is noted regarding a sign error in the voltage contribution from a 40-volt source, which should be -80/11 instead of +80/11. The key equations referenced include current/voltage division and Ohm's Law (V=IR), essential for accurate circuit analysis.

and adding all Vx I get 9.818181V.[/B]
You've got a sign error. The component of Vx produced by the 40 volt source is -80/11, not +80/11.
