# Different labels for different aligned parts of an equation

What is the best way to write something like this

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


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.

With empheq (which loads mathtools, hence amsmath):
\begin{empheq}[left={A=\empheqlbrace}]{align}
