Equation tags with subequations
8
Consider the following MWE:
documentclass{article}
usepackage{mathtools}
begin{document}
begin{align}
label{system}
&left{
begin{aligned}
30^{2} &= h_{C}^{2} + y^{2};\
40^{2} &= h_{C}^{2} + (50 - y)^{2};
end{aligned}
right.\
ArrowBetweenLines[Downarrow]
&left{
begin{aligned}
h_{C}^{2} &= 30^{2} - y^{2};\
h_{C}^{2} &= 40^{2} - (50 - y)^{2}.
end{aligned}
right.
end{align}
end{document}
I have two problems that I don't know how to solve:
- The equation tags are obviously not placed properly.
- I would like to label all four equation using the
subequationenvironment in order to get "(1a)", "(1b)", "(1c)", and "(1d)".
Thank you in advance.

May be as a first try with my so-called null hack (of course not beautiful ;)), you can achieve what you want within a subequation environment by overloading the empheq package (of course along with the amsmath package).
documentclass[10pt,a4paper]{article}
usepackage{mathtools}
usepackage{amsmath}
usepackage[overload]{empheq}
begin{document}
begin{subequations}label{e1}
begin{align}[left ={empheqlbrace}]
a = 1 &label{e1a}\
b = 1 &label{e1b}\
c = 1 &label{e1c}
end{align}
% the poor man's NULL hack :D
null\

begin{align}[left ={empheqlbrace}]
d = 1 &label{e1d}\
