How can I references equations that are on the same line? Here is an example:
\begin{align}
& a_{11} = b_{11}, & a_{12} = b_{12}, \label{eq1}
\\
& a_{21} = b_{21}, & a_{22} = b_{22}, \label{eq2}
\end{align}
If I have understood correctly, I can only reference the first or second line for this case. But I want to be able to reference each equation using \eqref. Is this possible?
