### Circuit Analysis Exercise

#### Problem Statement:
Determine the value for the voltage \( V_x \) using the following three methods:
1. **Nodal Analysis**
2. **Mesh Analysis**
3. **Thevenin's theorem** by finding the Thevenin equivalent circuit seen by the 4Ω resistor.

#### Circuit Description:
The given circuit features a combination of resistors, an independent current source, an independent voltage source, and a dependent current source. Refer to the circuit diagram below for component placement and connection:

- **Current Source**: 10A source
- **Voltage Source**: 100V source
- **Resistors**:
  - A 1Ω resistor in series with the 10A current source
  - Two 4Ω resistors in series-parallel configuration
  - A 6Ω resistor in series with the 100V voltage source
- **Dependent Current Source**: \( 2I_a \), where \( I_a \) is the current flowing through the 1Ω resistor

#### Diagram Analysis:

- The `10A current source` is located at the extreme left of the circuit.
- The `1Ω resistor` lies in series to the 10A current source, placed just to its right.
- The `\(I_a\)` denotes the current through the `1Ω resistor`.
- A `4Ω resistor` is connected in series immediately to the right of the 1Ω resistor.
- The node where the series 4Ω connects also branches upward to another `4Ω resistor`, continuing rightward.
- The rightmost 4Ω resistor connects to a `6Ω resistor`.
- The `100V voltage source` is depicted at the extreme right of the diagram, in series with the 6Ω resistor.
- At the central node between the two 4Ω resistors lies the voltage \( V_x \).
- The dependent current source \( 2I_a \) connects the bottom node with the central node where \( V_x \) is located.

##### Analysis Methods:

**A. Nodal Analysis:**
- Use Kirchhoff’s current law (KCL) to determine the node voltages.
- Express the current through each resistor in terms of node voltages and solve the resulting system of equations.

**B. Mesh Analysis:**
- Apply Kirchhoff’s voltage law (KVL) to each independent loop.
- Define mesh currents, set up equations according to
