(Please can you add the whole procedure? I do not finish understanding this topic and seeing all procedures will help me to better understand it.)
Let the following system be:

 The equivalent transfer function is given by: (the answer)
( Note: If we take a system with two zeros and two poles as an example, use the following format for your answer: k (as + b) (cs + d) / ((s + e) (s + f)) )

And the final value of y (t) before an inputis given by: (The answer)
(Note 2: Write the exact value, you can use fractional or decimal notation.)
