Why is the Step by Step function not offered for this math problem

Z0*(1+(-.3+.4i))/(1-(-.3+.4i)) with Z0=50

How do I get the Step by Step for the above equation? I dont see the value in paying $7 month if I cant get Step by Step for this fairly easy problem.

Thank you both for the replies. I am trying to watch the steps as the original equation 50*(1+(-.3+.4i))/(1-(-.3+.4i)) progresses toward the algebraic solution = 20.2703 + 21.6216 I

The teaching (and learning/refreshing) for me is all of the substitution etc. going on in a step by step process.

If you meant to replace Z0 by 50, then the command is

 Z0*(1 + (-.3 + .4 I))/(1 - (-.3 + .4 I)) /. Z0 -> 50
  (* 20.2703 + 21.6216 I *)

I do not know how to make Mathematica show step by step, but using Trace can show some of the steps performed internally

ClearAll[Z0]
Trace[Z0*(1 + (-.3 + .4 I))/(1 - (-.3 + .4 I)) /. Z0 -> 50] // TableForm (*to make it easier to see*)

What are you trying to do?

Z0*(1+(-.3+.4i))/(1-(-.3+.4i)) is not an equation? Z0=50 is an equation but is already 'solved' ?
