Hi All,

I got an function in the following form:

gl2[x_] := 
 b Subscript[e, 1] Subscript[e, 2] Subscript[t, 1] Subscript[t, 2] Subscript[t, K] (Subscript[\[Tau], xy]^\[Prime]\[Prime])[x] == 
  b Subscript[g, 
   K] (Subscript[e, 1] Subscript[t, 1] + 
     Subscript[e, 2] Subscript[t, 2]) Subscript[\[Tau], xy][x]

I am aming to reorder the Terms to the following Form:

gl2[x_] := (
    b Subscript[g, 
     K] (Subscript[e, 1] Subscript[t, 1] + 
       Subscript[e, 2] Subscript[t, 2]))/(
    b Subscript[e, 1] Subscript[e, 2] Subscript[t, 1] Subscript[t, 2]
      Subscript[t, K]) Subscript[\[Tau], xy][x] - \!\(
\(\*SubsuperscriptBox[\(\[Tau]\), \(xy\), \(\[Prime]\[Prime]\)]\)[
    x]\) == 0

Is there any way to tell mathematica to do this for me?.

Also I would like to Cancel the faktor b which is b!=0

Thanks for any help

Best regards,

Andreas Talmon
