Which best describes system $4?$

How many degrees of freedom does system $4$ have?

If you answered $($a$)$ to Q$12,$ write the system in linear matrix form $(=).$ If you answered $($b$)$ or

$($c$),$ write the system in explicit form $(()=0).$ If you answered $($d$)$ through $($f$),$ write it in $1$st order

explicit form, containing ODEs only. Do this even if the system is not square.

Write the name of an algorithm $($not the Matlab function$)$ that can be used to solve the type of

equations you wrote in the previous question, $($even if the system is unsolvable$).$

a$)$ linear algebraic equations $($AEs$)$ d$)$ ODEs

b$)$ bi$-$linear AEs e$)$ ODEs & linear AEs

c$)$ nonlinear AEs f$)$ ODEs & nonlinear AEs
