2. Consider the linear system of equations 2x1 - 62 -23 = -38 -3x1 - 22 + 723 = -34 -8x1 + 22 - 223 = -20 a) With an initial guess x) = [0, 0, 0]apply, by hand, the Jacobi iteration until the approx- imate relative error falls below 7%. b) With the same initial guess as in a), solve the system using Gauss-Seidel method
