I cooked this up in two minutes - it's more than a little ugly and can
surely be improved - sorry, no time to explain it.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\addtocounter{equation}{-1} \left. \parbox{0.75\textwidth}{% \vspace{-\baselineskip} \begin{subequations} \begin{align} 2+2&=3 \\ 1+3&=4 \\ 5+3&=7 \end{align} \end{subequations} \vspace{-1.5\baselineskip} } \quad \right\}
\end{document}

Cheers,  Phil
