While labeling the equation and figures, I want to enter different equation number instead of automatic equation number. How can I do that?
Code;
(Eq.~\ref{eq:xyz}):
\begin{equation} \label{eq:xyz}
\frac{W_e}{W_o}=A{W_o}^cK_{vs}\ .
\end{equation}

You question is quite unclear and unfortunately does not contain a 
minimal working example (correctly marked as code) to make it somehow self explaining. So I can only guess: Maybe you are searching for 
amsmath command

If I reply to any other topic or if you've not yet added a minimal working example, please do not expect any further response. And please don't forget to tag examples as code.
