Let you consider the following linear equation system.

$-2x_1+5x_2+4x_3-3x_4=9$

$x_l-7x_2+2x_3+9x_4=7$

$4x_l+3x_2+8x_3-6x_4=0$

$-6x_1+15x_2+12x_3-9x_4=27$

You are requested to solve system if possible.

a$)$ Sketch the flow diagram

b$)$ Write the MATLAB Code on the answer sheet to solve this equation system by finding its determinant and its inverse.

c$)$ Add explanation $($comment$)$ for each line of this MATLAB Code.

d$)$ Run the $m-$script and show the screenshots using the "print screen" button on the keyboard.

e$)$ Discuss what it can be said about the matrix in terms of its determinant and in terms of its inverse.
