Answer should be -8.25 V

**Figure 9-37: Circuit Schematic for Problem 9.20**

This schematic represents a complex circuit with multiple resistors, operational amplifiers, and voltage sources. The objective is to determine the output voltage \(V_o\) from the given inputs.

### Circuit Components and Configuration:

1. **Voltage Sources:**
   - A 2V source connected to the top left of the circuit.
   - A 1V source connected to two points in the left section.
   - A 5V source connected at the bottom left.

2. **Resistors:**
   - The circuit contains various resistors with the following resistance values:
     - 1 kΩ
     - 3 kΩ
     - 2 kΩ
     - 1.5 kΩ
     - 1.2 kΩ
     - 2.4 kΩ
     - 4.8 kΩ
     - 1 kΩ
     - 3 kΩ
   
3. **Nodes and Voltages:**
   - The circuit is divided into nodes labeled from \(V_1\) to \(V_8\):
     - \(V_1\), \(V_2\), and \(V_3\) are between the top resistors.
     - \(V_4\) and \(V_5\) appear before the operational amplifiers. 
     - \(V_6\), \(V_7\), and \(V_8\) are located between the resistors connected to the 5V source (bottom section).

4. **Operational Amplifiers:**
   - The circuit contains two operational amplifiers configured in the signal paths leading to the output \(V_o\).
   
### Diagrams Explanation:

- **Top Section:**
  - Begins with a 2V input through a 1 kΩ resistor leading to \(V_1\).
  - Connects serially through 3 kΩ and 2 kΩ resistors leading to \(V_2\) and \(V_3\), respectively.
  - Continues through a 1.5 kΩ resistor parallel with the 1V source.
  - Ends at the input terminal of an operational amplifier, through 4.8 kΩ to \(V_4\), and 2.4 kΩ to a shared node with the output line.
