**Circuit Analysis**

Diagram Description:
A circuit diagram features several components and is used to determine the value of \( V_o \). The components and their connections are detailed as follows:

1. **Voltage Sources:**
   - A 4V voltage source is connected to the left side of the circuit.
   - A 5V voltage source is connected to the right side of the circuit.

2. **Resistors:**
   - A 5-ohm resistor is in series with an unknown voltage \( V_x \).
   - A 2-ohm resistor is connected between the junction of the 5-ohm resistor and a dependent current source.
   - A 4-ohm resistor is connected in series with the 2-ohm resistor and across the 5V source.
   - A 4-ohm resistor is also connected vertically between the 4V source and the center node, where the 3 \( V_x \) current source and resistor networks meet.

3. **Current Sources:**
   - A 4A independent current source is connected to the left portion of the circuit.
   - A dependent current source of 3 \( V_x \) is present on the right-hand side of the circuit.

**Questions:**

**(a)** If you use the *node-voltage method*, how many independent equations will you need?
**(b)** If you use the *mesh-current method*, how many independent equations will you need?
**(c)** Based on the results from (a) and (b), which method would you prefer to use to solve this circuit, *node-voltage* or *mesh current*?
**(d)** Use the preferred method you find from (c) to determine the value of \( V_o \).
