Using MATLAB, create matrices and solve the following equations. Put the datetime command in the command window to show the date and time, and take a screenshot$($s$).$ Then submit an image file$($s$).$

Find $x,y,z$

$2x+y+3z=-2$

$xy-z=-3$

$3x*2y+3z=-12$

Find $u_2,u_2,u_3,u_4,$ and $u_5.$

$2u_1+u_2+u_3+u_2+u_1=4$

$u_1+2u_2+u_1+u_2+u_2=5$

$u_1+u_2+2u_3+u_4+u_1=6$

$u_1+u_2+u_3+2u_2+u_1=7$

$u_1+u_2+u_2+u_a+2u_1-8$
