Solution

The image you uploaded contains a system of linear equations to be solved using the Gauss-Seidel method, and you're asked to perform 4 iterations and evaluate the error at step 4.

The system of equations:

10x_1 - 2x_2 - 3x_3 &= 20 \\ -2x_1 + 20x_2 - 5x_3 &= 40 \\ x_1 - 3x_2 + 10x_3 &= 8 \end{aligned}$$ ### To solve using the **Gauss-Seidel method**, we'll follow these steps: 1. **Rearrange each equation** to isolate $$x_1$$, $$x_2$$, and $$x_3$$: $$x_1 = \frac{20 + 2x_2 + 3x_3}{10}$$ $$x_2 = \frac{40 + 2x_1 + 5x_3}{20}$$
