How to align a variable whose sign is absent with a variable whose sign is present while both are inside...
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.
This is what I'm looking for (from a book):
xetex positioning amsmath

I don't understand why there is a ban onphantom
here? It seems like an ideal place to use it. All other options will just require more work-around and more code...

Since you banned phantom
....
documentclass{article}
usepackage{amsmath}
begin{document}
[
|x|=left{
begin{array}{rl}
a &text{if dots}\
- a &text{if dots}
end{array} right.
]
end{document}
Notes:
`standalone' is not for this purpose
use [ ] for display math (or the equation environment if numbered)
There is nothing wrong with
phantom
Needstandalone
andgathered
oraligned

Thank you. I am disappointed that, based on the answers, nothing can be done inside thegathered
