Problem 1 Solve the following system of linear algebraic equations: 811 + 2x9 + 313 = 51 211 + bxo + 13 = 23 3x1 +x2 + 623 = 20 Use the Jacobi iterative method. Carry out the frst four iterations using a calculator. Show all Case 1. steps including the values of residuals for each equation. (20 points). Case 2. Use the Gauss-Seidel iterative method. Carry out the frst four iterations using a calculator. Show all steps including the values of residuals for each equation. (30 points). e NOTE: Use at least 5 digits after the decimal point in all calculations
