So I'm trying to do a simple thing with cases:
$
\begin{cases}
-x+5y&=6\\
x-3y&=-4\\
\end{cases}
\\
\begin{cases}
-x+5y&=6\\
x&=3y-4\\
\end{cases}
$
And of course, LaTeX doesn't do what it should. For some reason, the "x" is far to the left.
How to make it look centered around the equal sign?
cases
is for the “conditions”, not for aligning equals signs.
