To find the Thevenin voltage (\( V_{th} \)), we need to determine the open-circuit voltage across the terminals where \( R_L \) is connected. Let's analyze the circuit step by step:

### Circuit Recap:
- We have a circuit with resistors, voltage sources, and current sources.
- We want to find the open-circuit voltage across the terminals where \( R_L \) is connected, which will be our \( V_{th} \).

### Steps to Find \( V_{th} \):

1. **Label the Circuit**:
   - Identify the terminals across which \( R_L \) is connected. We'll calculate the voltage across these terminals with \( R_L \) removed (open circuit).

2. **Simplify the Circuit**:
   - Calculate the voltage across the terminals considering the effect of all the sources.

3. **Use Superposition**:
   - If the circuit has multiple sources, it can be useful to apply the superposition principle, where we consider the effect of each source separately and then sum the results.

### Detailed Calculation:

#### **Step 1: Identify Open-Circuit Voltage (\( V_{th} \))**

We'll focus on the circuit to find the open-circuit voltage across the load resistor, which is the voltage across the terminals when \( R_L \) is not connected.

#### **Step 2: Analyzing the Circuit**

Let's denote the terminals where \( R_L \) was connected as \( A \) and \( B \). We need to find the voltage \( V_{AB} \), which is \( V_{th} \).

**Step 3: Apply Kirchhoff's Voltage Law (KVL) or Nodal Analysis**

- We can use Nodal Analysis to find the voltage at point \( A \) with respect to \( B \).

Let’s break down the approach:

1. **Determine the currents** from the current sources and the voltages across each resistor.

2. **Calculate the voltage at point \( A \)** with respect to ground using the voltage sources and resistors.

3. **Find \( V_{AB} \)**, which is \( V_{th} \).

#### **Step 4: Superposition Principle (if necessary)**

If there are multiple independent sources, consider the contribution of each to the voltage across \( AB \).

#### **Step 5: Calculate \( V_{th} \)**

- Combine the effects of each source (if using superposition) or directly calculate using the methods above.
