For now, you may not use any of the powerful functions available in python modules, with two exceptions: you may import functions from the math module and the copy module.You must include reasonable comments in your code.

d) Write a function defined as:lef GaussElim (Aaug): Purpose of Gaussalim (Aaug): use the Gauss Elimination with Back Substitution method to solve the set of linear equations expressed in matrix form as Ax=b. Both A and b are contained in the function argument - Aaug. Aaug: an augmented matrix containing [Ab ] having N rows and N+1 columns, where N is the number of equations in the set. return value: x - an array of size N, containing the solution to Ax= b Notes: Do NOT use partial pivoting in this program. (I want everyone to get the exact saane answer, and I don't want you working quite that hard). Write and call a main() function that uses your Gausselin function to calculate and print the solution to the same sets of linear equations given in part c). MyA = [[4,-1,-1, 3], [-2, -3, 1,9], [-1, 1, 7,-6]] using initial guesses of all zeros. Perform 22 iterations. another A = [[4, 3, 1,-1, 2], [2,-5, 0, -2, -3], (-3, 3, -6, 1, 5), [0, 1, 4, 8, -2]] using initial guesses of all zeros. Perform 3 iterations
