Space in array system equations
I need to make some system equations but when I place them on one row I have this problem. Space between |
and x
. How to remove it?
begin{document}
Example 1:
\
$left| begin{array}{@{}*{4}{c@{,}}l}
2x+3y-cancel{z}=4 \
3x+2y+2=6
end{array}right.$
textrightarrow
$; 5x+5y=10$ textrightarrow
$; x+y=2;$
$;$ % Space
$left| begin{array}{@{}*{4}{c@{,}}l}
x-y+2z=2 \
3x+2y-z=4 | .2
end{array}right.$
textrightarrow

You can better exploit array
:
documentclass{article}
usepackage{amsmath,array,cancel}
newenvironment{system}[1]
{%
left|setlength{arraycolsep}{0pt}
begin{array}{ @{} *{numexpr2*#1relax}{ >{{}} r <{{}} } l @{} }%
}
{end{array}right.}
begin{document}
$begin{system}{3}
2x &+& 3y &-& cancel{z} &=& 4 \
3x &+& 2y &+& cancel{z} &=& 6
end{system}
rightarrow
5x+5y=10
rightarrow
x+y=2
rightarrow
begin{system}{3}
x &-& y &+& 2z &=& 2 \
3x &+& 2y &-& z &=&4 mid .2
end{system}$
end{document}
This way the unknowns are perfectly aligned to each other. The argument to system
specifies the number of unknowns.

It is quite simple to type it with the systeme
package:
documentclass{article}
usepackage{amsmath, cancel, systeme}
begin{document}
[ sysdelim | .
systeme{2x + 3y-cancel z = 4,3x + 2y + z = 6} longrightarrow 5x + 5y = 10 longrightarrow x + y = 20 longrightarrow systeme{x-y + 2z = 2, 3x + 2y - z = 4|. 2} ]%

I suggest you load the mathtools
package and use its matrix*
environment instead of the second array
, along with three well-placed phantom
instructions. I would also replace .2
with cdot2
.
documentclass{article}
usepackage{cancel,mathtools}
newcommandwideto{quadtoquad}
begin{document}
noindent
Example 1:
begin{align*}
renewcommandarraystretch{1.333}
&leftvertbegin{matrix}
2x+3y-cancel{z}=4 \
3x+2y+cancel{z}=6
end{matrix}right.
wideto
5x+5y=10
wideto
x+y=2
; \
&leftvertbegin{matrix*}[l]
phantom{3}x-phantom{2}y+2z=2 \
3x+2y-phantom{2}z=4 ;| cdot2, {}+{}
end{matrix*}right.
wideto
7x+3y=10
wideto
x+tfrac{3}{7}y=tfrac{10}{7};
end{align*}

This way the unknowns are perfectly aligned to each other. The argument to system
specifies the number of unknowns.
