please help. thank you

3. Consider the simultaneous equations f(x, y, z) = (ay-23 - 1) = 0, 12(x, y, z) = (xy? +222 - 154) = 0, f366, y, z) = (2y2 + 2-6) = 0. (a). Obtain the Jacobian matrix for the system of equations. (b). For initial guesses * = 2, y = 2, and 2 = 2, obtain one solution, a set of x, y, and 2, using Matlab function fsolve. (c). Obtain a master equation in y by expressing in terms of yr in terms of y, and finally two relations for 2 in terms of y. Identify all roots of the master equation using the Matlab function roots(coeff). Obtain the corresponding x and (d). Try to obtain all real roots of the system of equations using Matlab function fsolve
