Please check whether this meets your needs:
\usepackage{amsmath}
\begin{equation*}
\setlength{\arraycolsep}{0pt}
\renewcommand{\arraystretch}{1.25}
\begin{array}{r@{\;}c@{\;}r@{\;}}
x+y+2 & = & 1\\
2x+3y-4z & = & 2\\
\hline
\multicolumn{1}{|r@{\;}}{3x-2y+z}
& \multicolumn{1}{c@{\;}}{=}
& \multicolumn{1}{r@{\;}|}{3}\\
\hline
\end{array}
\end{equation*}
