Question#2[4+6=10 marks] (a) Find the first two iteration of Gauss and Seidel method of the following system of linear equations. 4x1 + x2 - X3 = 5, -x1 + 3x2 + *3 = -4, 2x1 + 2x2 + 5x3 = 1. (b) Find the first two iterations of the SOR method with w = 1.1 for the following linear systems, using x) = 0: 4x1 + x2 - x3= 5, -x1 + 3x2 + x3 =-4, 2x1 + 2x2 + 5.x3 = 1
