First note that

In[15]:=
a*b=c/d

>From In[15]:=
\!\(\*
  RowBox[{\(Set::"write"\), \(\(:\)\(\ \)\), "\<\"Tag \\!\\(Times\\)
in \\!\\(
      a\\\\ b\\) is
      Protected. \\!\\(\\*ButtonBox[\\\"More...\\\", \
ButtonStyle->\\\"RefGuideLinkText\\\", ButtonFrame->None, \
ButtonData:>\\\"General::write\\\"]\\)\"\>"}]\)

Out[15]=
c/d

Not sure exactly what do you want. Anyway...

In[28]:=
HoldForm[a*b = c/d]
(% /. HoldForm[x_ = y_] :> Solve[x == y, x[[1]]])[[1,1]] /. (x_ -> y_)
-> HoldForm[x = y]

Out[28]=
HoldForm[a*b = c/d]

Out[29]=
HoldForm[a = c/(b*d)]

Dimitris
