please provide full working examples not only fragments.
\nccurve makes more sense here:

\listfiles
\documentclass{article}
\usepackage{pst-node,amsmath,array}

\begin{document}

\begin{center}
$\arraycolsep=1.4pt\def\arraystretch{1.6} \begin{array}{r c l c r c l} & & & \left| 5-3x \right| \rnode{C3}{\,\le\,} 7 \\[7mm] 5-3x & \rnode{L3}{\le} & 7 & \text{\textbf{or}} & -\left(5-3x\right) & \rnode{R3}{\le} & 7 \\ 5-3x-5& \le & 7-5 & & -5+3x & \le & 7 \\ -3x & \le & 2 & & -5+3x+5 & \le & 7+5 \\ -\dfrac{1}{3} \cdot -3x & \ge & -\dfrac{1}{3}\cdot 2 & & 3x & \le 12 \\[2mm] x & \ge& -\dfrac{2}{3} & & \dfrac{1}{3}\cdot 3x & \le &\frac{1}{3}\cdot 12 \\[1mm] & & & & x & \le & 4 \end{array}$
\end{center}
\psset{nodesep=3pt}
\nccurve[angleA=-110,angleB=70]{->}{C3}{L3}
\nccurve[angleA=-70,angleB=110]{->}{C3}{R3}
\end{document}
