using Matlab please

Problem 3 Solve the twenty-one systems of equations: (70+ y + 2z = 0.01m? - 2m 2 - 5y +23 = 2 - m 2x + y + 529 obtained by setting, in turn, the value of the quantity m on the right-hand side to all integers in between, and including, m = 0 and m = 20. This time use the LU-decomposition of the systern matrix that is implemented in MATLAB by the lu function. Perform the decomposition only once, then use the lower and upper-triangular factors repeatedly to find each successive solution. Turn in the code and a plot of the first and second components of the solution that is, the values of and y) as a function of the right-hand side parameter m
