I have two equations like

\begin{equation}
a
\end{equation}
\begin{equation}
b
\end{equation}

I need the equations to be numbered as (1a) and (1b). How to do that? Can anybody help me to solve this?

\begin{subequations} and \end{subequations} are not working sir. It shows some error. – user166814 Aug 01 '18 at 18:05
