Maybe I misunderstand you, but I do not think cases is right here.
Also, are you sure you want to group two equations but only number one
of them.

If I understand you correctly, I'd try with one of these, depending on
if citing the group or one of the equations.

\starttext

\startformula
  \startalign[location=packed,fences=sesac]
    \NC \[21-(9 - n^2)\NC =□^\prime\]\NR
    \NC  n^2+12 \NC=□^\prime.        \NR
  \stopalign
  \numberhere[eq:foo]
\stopformula

\startplaceformula
  \startformula
    \startalign
      \NC \[21-(9 - n^2)\NC =□^\prime\]  \NR%[eq:bar-a]
      \NC  n^2+12 \NC=□^\prime.          \NR[eq:bar-b]
    \stopalign
  \stopformula
\stopplaceformula
