It's a MatLAB , matlab question. Can you solve asap

G=2

H=7

I=6

Perform the following in MATLAB Language (Write appropriate MATLAB scripts only, no solution required) a. Find the unknowns x and y in Matrix form: 2x - 5y = 3 and x+y=-1 b. Find the unknowns x and y using symbolic MATLAB: 2x - 5y = 3 and x +y = -1 c. Find the roots of the polynomial: -(I +1)x + (H + 3)x + (6 + 2)x5 = 0 d. Define a linearly spaced vector in the range of [0,300] with 100 elements and assign it to the variable "z". e. Using the variable z" created in Question 1.d, please write the script to plot x vs. y = 23
