30 pts P3 Use Python to solve the following system with the Gauss-Seidel method until the percent relative error for all variables falls below & = 5%: 10x + 2x - X3 - 3x X3 = 27 6x + 2x3 = -61.5 -21.5 x + x + 5x3 = (a - 15 pts) Provide your code and the iterations printout with updated variables' values (x1, x2, x3) and final solution (b - 15 pts) Repeat (a) by using the Jacobi variant (a small change in your code is required)
