# Adding an brace at the right of equation numbering

I use the following:

\documentclass{article}
\usepackage{amsmath}
\begin{document}
$$\label{eq:solve} x^2 - 5 x + 6 = 0$$

$$x_1 = \frac{5 + \sqrt{25 - 4 \times 6}}{2} = 3$$

$$x_2 = \frac{5 - \sqrt{25 - 4 \times 6}}{2} = 2$$
\end{document}


to display:

How can I add an brace with a text on the right of the equation numbering? Like the following:

Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Christian Hupfer Jun 17 '14 at 21:36
@ChristianHupfer Good idea, thanks! – Franck Dernoncourt Jun 17 '14 at 21:43
Accolade is mainly a "false friend". The correct English word is "brace" – Jubobs Jun 17 '14 at 22:35

This is one way:

\documentclass{article}
\usepackage{mathtools}
\begin{document}
$\begin{drcases*} \begin{minipage}{0.7\textwidth} $$\label{eq:solve} x^2 - 5 x + 6 = 0$$ $$x_1 = \frac{5 + \sqrt{25 - 4 \times 6}}{2} = 3$$ % don't leave blank line $$x_2 = \frac{5 - \sqrt{25 - 4 \times 6}}{2} = 2$$ \end{minipage} \end{drcases*} \text{bla bla bla}$
\end{document}

+1 for introducing me drcases. – Sigur Jun 17 '14 at 22:43
