Uhm, vertical or horizontal spacing?

There sure is.  Try playing about with the two numbers in the following
until you get what you want.  If you use the same construction over you
might want to place the two commands in the preamble. The \\[0pt] can be
used to change line separations individually.

\begin{equation}
\arraycolsep0pt
\renewcommand\arraystretch{1}
\begin{array}{lclcr}
  ax & + & by & = & 20 \\ %[0pt] % uncomment and change 0pt
  ax & - & by & = & 10 \\ %[0pt] % to what you need
  \hline
     &   & ax & = & 10
\end{array}
\end{equation}
