Space in array system equations












5















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?
enter image description here



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
end{document}

          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.

            Rather than eliminating the space, I propose working instead to align columns in the systems of equations. Also, by making it one big math expression, the spacing also takes on a more natural appearance.



            documentclass{article}
            usepackage{array,amsmath,cancel,tabstackengine}
            setstacktabulargap{0pt}
            TABstackMath
            begin{document}
            noindent Example 1:
            \
            $left| tabularCenterstack{rrrl}{
            2x+&3y-&cancel{z}=&4 \
            3x+&2y+&cancel{z}=&6
            }right.
            rightarrow
            5x+5y=10 rightarrow
            x+y=2;
            left| tabularCenterstack{rrrl}{
            x-&y+&2z=&2 \
            3x+&2y-&z=&4 | .2
            }right.
            rightarrow$
            end{document}

              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} ]%

              end{document}

                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.



                enter image description here



                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*}

                      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.

                          Rather than eliminating the space, I propose working instead to align columns in the systems of equations. Also, by making it one big math expression, the spacing also takes on a more natural appearance.

                                          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.

                                            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.
