    Welcome to TeX.SE. What is the issue? The left-alignment of the equations? – user31729 Jan 8 '17 at 19:44

    Please make small complete document, which will show your issue. For sub equations: need to load amsmat or mathtools package and than in your case use \begin{sunequations}\\begin{gather}equation 1 \\ equation 2 \\ etc \end{gather}\end{subequations} ... – Zarko Jan 8 '17 at 19:54
  • sorry i am not getting clearly...in this case where can i put my paragraph text?? I need to produce exactly as given in snapshot. – Ashu Jan 8 '17 at 21:57

You can use \tag for the main equation:


% detach \eqref and \tag making

  \maketag@@@{\textup{Eq.\ }(\ignorespaces#1\unskip\@@italiccorr)}%



\lipsum*[3]% the paragraph before the equation
PR+c\delta t^s=\dots \tag{\ref{eq:PR+cdeltat}}
\lipsum*[4]% the paragraph between the equations
P_1&=\dots \\
P_2&=\dots \\
P_3&=\dots \\
\lipsum[5]% text that follows


enter image description here

I'd avoid “Eq.” before the equation numbers: your readers will know what that number is for. Just remove the code from \makeatletter and \makeatother if you choose to do this way.

You will use \eqref{eq:PR+cdeltat} for referring to the equation number, like in

Thus, four unknowns in~\eqref{eq:PR+cdeltat}, the three unknowns ...
