Thanks fo rthe explanations: indeed with my previous setups for having each exercise with a vertical rule at its left, the following modification works fine when I need items in two columns:

\startsimplecolumns
\startitemize[r,packed][margin=standard,stopper=,left={(},right={)},distance=1em]
\item $3x - 5 = 4$.
\item $(x-1)(x+3) = 5$.
\item $2 - 3x \geq 2 x - 8$.
\item $(x - 1) \leq (x-1)(x+2)$.
\item $2x^2 - 3x +1 < 0$.
\item $x^2 - 4x \geq x - x^2 - 1$.
\stopitemize
\stopsimplecolumns

Best regards: OK
