a) For the following set of linear equations:10x? + 25x2x3 = 2-3x? - 6x? + 2x3 = -6x? + x2 + 15x3 = -4a) Show two iterations of the Gauss Siedel Method. Use an initial guess of x? = x3 = 0.5. Show yourcalculations in MATLAB.b) Show two iterations of the Jacobi method to solve these linear equations. Use an initial guess of x? = x? = X3 = 0.5.c) Which method produces a solution closest to the actual solution after 2 iterations?
