Hi all,

I use the following construct for exercises (attachment) and would like to save some space saved, like in the second example. Is there a trick/command/setup one can use?

\defineitemgroup [TA] % TeilAufgabe
\setupitemgroup  [TA] [symbol=a,stopper=)]

% \setupformulae[spacebefore=-12pt] % ,alternative=single

\starttext \showframe

example 1:
\startTA[columns]
\item \startformula \startalign
        y & \leq -2x+5 \\
        y & > 2        \\
        x & \leq 3
      \stopalign \stopformula
\item \startformula \startalign
        2x-y & \leq 6 \\
           y & < 3    \\
           y & \geq -x
      \stopalign \stopformula
\stopTA

\blank[2*big]

example 2:
\startTA[columns]
\item \vskip-2.5\lineheight
  \startformula \startalign
    y & \leq -2x+5 \\
    y & > 2        \\
    x & \leq 3
  \stopalign \stopformula
\item \vskip-2.5\lineheight
  \startformula \startalign
    2x-y & \leq 6 \\
       y & < 3    \\
       y & \geq -x
  \stopalign \stopformula
\stopTA

\stoptext
