What is the best way to write something like this

\begin{equation}
A=
\left\{
\begin{aligned}
& B\\
& C
\end{aligned}
\right.
\end{equation}

but with two different labels (i.e. equation numbers) for the two right-hand lines after the brace? I am considering several options (like using alignat), not sure what is the best and easiest way to accomplish this result.

    It that is a case-like structure, have a look at the cases package. – muzimuzhi Z Sep 20 '20 at 11:10

With empheq (which loads mathtools, hence amsmath):

\begin{empheq}[left={A=\empheqlbrace}]{align}
&B \\ &C
\end{empheq}
