**Problem Statement:**
3- Find Vo in the below Circuit

**Circuit Description:**

This diagram illustrates an operational amplifier circuit with multiple resistors and voltage sources. The circuit components are as follows:

1. **Voltage Sources:** 
   - Two 5V voltage sources are connected in the circuit. One is on the left side connected to the non-inverting input (+) of the operational amplifier, and the other is directly connected to one of the nodes connected to a 20kΩ resistor.

2. **Resistors:** 
   - A 10kΩ resistor is connected in series with the first 5V source.
   - A 40kΩ resistor is placed between the inverting input (-) and the non-inverting input (+) of the operational amplifier.
   - A 20kΩ resistor is connected in parallel with the above-mentioned 40kΩ resistor, extending to ground.
   - Another 20kΩ resistor is connected in series with the second 5V source and the node connected to the inverting input of the op-amp.
   - A 10kΩ feedback resistor is connected from the output (Vo) to the inverting input of the operational amplifier.

**Operational Amplifier:**
- The op-amp has an inverting (-) and a non-inverting (+) input.
- The non-inverting input is connected to the junction of the 10kΩ and 40kΩ resistors.
- The inverting input connects to the node where the other 20kΩ resistor and the second 5V source meet.
- The output is labeled Vo.

**Objective:**
- Calculate the output voltage, Vo, of the circuit. 

**Analysis:**
An analysis of nodal voltages, current flows, and application of virtual short concept may be needed to find Vo using the known properties of operational amplifiers and circuit theory.
