PROVIDE MATLAB CODE PLEASE!!

Consider the following system of equations.

$4a-2b+3c-d=-6$

$3d+b-2c-29=0$

$5b-c-3a-d=4$

$2a-9+5c=0$

a$.[20$ pts$]$ Solve the system of equations using the matrix method. $($Note: you must create the matrix A and the vector $B$ without using built$-$in functions$)$

b$.[20$ pts$]$ Solve the system of equations using symbolic variables.$]$
