How to align a variable whose sign is absent with a variable whose sign is present while both are inside...












0















I can't seem to align variables properly since one of them leaves its sign behind on alignment.



documentclass{standalone}
usepackage{amsmath}
begin{document}

% NO ALIGNMENT
$begin{gathered}
|x|=
begin{cases}
amedspace{}text{if dots}\
-amedspace{}text{if dots}
end{cases}
end{gathered}$

% IMPROPER ALIGNMENT
$begin{gathered}
|x|=
begin{cases}
&amedspace{}text{if dots}\
-&amedspace{}text{if dots}
end{cases}
end{gathered}$

end{document}




For your reference, I would like to avoid using phantom as well as complicated macros.
