can you answer part e only using MATLAB code please

You are given the following system of equations: --3x; + x2 + 12x3 = 50 6xy - x2 - xy = 3 6x; + 9x2 + x3 = 40 a. What are the rank and the condition number of the coefficient matrix for the system? b. If justified, solve the system of equations via a direct inverse C. Solve the system of equations using LU decomposition d. Solve the system of equations using the Jacobi method until the percent estimated relative error falls below 0.1%. Use zeros as initial values. If necessary, re-arrange the equations to achieve convergence e. Repeat d) using the Gauss-Seidel method
