Profressor didn't fully explain what codes to use or matlab tools that can help.

The ztrans function could be useful here —

syms n t x(n) X(z) y(n) Y(z) z 
Eqn1 = y(n) == 2*y(n-2) + y(n) + x(n)

Eqn1 = 

Eqz1 = ztrans(Eqn1,n,z)

Eqz1 = 

Eqz1 = simplify(Eqz1, 500)

Eqz1 = 

Eqz1 = subs(Eqz1, {ztrans(x(n),n,z),ztrans(y(n),n,z)}, {X(z), Y(z)})

Eqz1 = 

Eqziso = isolate(Eqz1, Y(z))

Eqziso = 

Experiment!
