Use the Gauss-Seidel method (a) without relaxation and (b) with relaxation (? = 1.2) to solve the following system to a tolerance of ?s = 5 %. If necessary, rearrange the equations to achieve convergence. 4x1 - 6x2 - x3 = -38 -6x1 - x2 +7x3 = 34 -16x1 + x2 - 2x3 = -20

Step 1
The rearranged equations are: x1 = (6x2 + x3 + 38) / 4 x2 = (6x1 - 7x3 - 34) / -1 x3 = (16x1 + x2 + 20) / 2 (a) Gauss-Seidel method without relaxation: We start with initial guesses for the variables. Let's assume x1 = x2 = x3 = 0. Show more…
