I tried to use the following commands
- Code: Select all • Open in writeLaTeX
`\begin{equation}\label{xx} 3+4=7 \end{equation}` Referring to the equation \eqref{xx}
or - Code: Select all • Open in writeLaTeX
`\begin{equation}3+4=7 \label{xx}\end{equation}` Referring to the equation \eqref{xx}
but it did not work... it worked just if instead of `\eqref{xx}` I wrote `\ref{xx}` . Why is it so? Should I use a particular package? N.B I am using Texniccenter and Mixtek as a compiler- beth87

"It doesn't work" is an error description that is as good as useless. What is the exact error message from the log? As a random shot I would guess that you forgot to load the amsmath package.
