i need help using matlab please. please follow the instructions, solve everything. thank you.

3. Consider the simultaneous equations S=(, y, z) = (xv? + x22 - 15y) = 0, 13(x, y, z) = (2y +32-6) -0. (a). Obtain the Jacobian matrix for the system of equations. b). For initial gueses 2 = 2y = 2, and 3 = 2, obtain one solution, a set of x, y, and using Matlab function solve. (c). Obtain a master equation in y by expressing in terms of y, in terms of y, and finally two relations for in terms of Identify all roots of the master equation using the Matlab function roots(coet). Obtain the corresponding and (d). Try to obtain all real roots of the system of equations using Matlab function folve
