write four linear algebra functions using for$-$loops or

while$-$loops. The four linear algebra functions you will write are $1($Ax$=$b$),$ and

matrix$-$matrix multiply $($AB$=$C$)$b$,$ and the result from the matrix$-$matrix

multiply, which is the matrix C x$\_(1)=[[8],[2],[10],[17]]$ and x$\_(2)=[[1],[30],[11],[6]].$A$=[[-4,15,2,7],[1,8,21,12],[10,6,11,14],[17,9,4,23]],$ and B$=[[5,17,6,3],[20,9,27,1],[11,2,23,24],[8,24,2,27]]$

Can someone please help write this in a Python code in Jupyter Notebook. Thank you
