**Problem Statement:**

6. For the circuit shown below, use node-voltage equations to solve for \( V_x \) and \( I_x \).

**Circuit Diagram Description:**

- The circuit consists of a voltage source \( V_s = 15 \, \text{V} \).
- There are five resistors with the following resistances:
  - \( R_1 = 2 \, \text{k}\Omega \)
  - \( R_2 = 500 \, \Omega \)
  - \( R_3 = 500 \, \Omega \)
  - \( R_4 = 2 \, \text{k}\Omega \)
  - \( R_5 = 750 \, \Omega \)

- The nodes are labeled as follows:
  - \( V_a \) is the node at the top of \( R_1 \) and \( R_2 \).
  - \( V_b \) is the node between \( R_3 \) and \( R_4 \).
  - \( V_c \) is the node between the positive terminal of the voltage source and \( R_3 \).

- The voltage \( V_x \) is across \( R_5 \), and the current \( I_x \) flows through \( R_2 \).

- The diagram shows the flow of current \( I_x \) from top to bottom through \( R_2 \), indicated by a blue arrow.

**Instructions:**

To solve for \( V_x \) and \( I_x \), apply node-voltage equations based on the connections and resistances shown in the circuit. Use the following key points:
- Apply Kirchhoff's laws at each node to set up equations.
- Solve the system of equations for the unknown node voltages.
- Use Ohm’s law to find \( V_x \) and \( I_x \) once node voltages are known.
