## Homework Statement

I attached the question. We have to use

**superposition**to find the value of Vo.

## Homework Equations

Rt = R1 + R2 + R3 + ... + Rn in series.

(1/Rt) = (1/R1 + 1/R2 + 1/R3 + ... + 1/Rn)^-1 in parallel.

Current divider = (Rx/Rt)*Is

Voltage divider = (Vx/Vt)*Vs

## The Attempt at a Solution

To find the value of Vo, I know I have to first replace the voltage source only with a short circuit and find Vo'.

Then remove the current source only with an open circuit and find Vo".

Then Vo = Vo' + Vo".

The problem I have is the setup of the resistors. How do we know what is in parallel/series with what? My teacher solved this question by shifting the resistors around but I did not understand that. Any tips for finding the total resistance where a setup of resistors similar to this would be appreciated.

If I can understand how to find the total resistance I should be able to solve this problem.
