rform the following in MATLAB Language
(Write appropriate MATLAB scripts only, no solution required)
a. Find the unknowns x and y in Matrix form: 3x – 5y = 7 and 2x + y = -4
b. Find the unknowns x and y using symbolic MATLAB: 5x – 2y = 9 and 7x + 8y = 11
c. Find the roots of the polynomial: -(H + 8)x + (! + 3)x² + (C + 1)x³ = 0
d. Define a linearly spaced vector in the range of [0,200] with 100 elements and assign it to
the variable “z”.
e. Using the variable “z” created in Question 1.d, write the script to plot z vs. y = 3z.
