Novak:
The following is not particularly elegant but it works. The main
problem with the following solution is that there is no direct way to
refer to one of the subequations using a label.
Francesco.

\begin{equation}
\renewcommand{\theequation}{\arabic{equation}a,~b}
\label{eq:pippo}
1 = 1
\quad\text{and}\quad
2=2
\end{equation}
With the above solution, when you need to refer to a subequation, you
will need to do it as follows:
As you can see in Eq.~(\ref{eq:pippo}a), bla bla bla \ldots
i.e., you need to explicitly type the `a' or `b'.
