next beta:

\starttext

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\startformula \startalign
     \NC c - a     = \NC b \NR
     \NC d + c - b = \NC a \NR
\stopalign \stopformula

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\startformula
\mframed
     [offset=1mm,loffset=3mm,roffset=3mm] {
         a + b = c
     }
\stopformula

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\startformula
\mframed
     [offset=1mm,loffset=3mm,roffset=3mm] {
         \startalign
             \NC c - a     = \NC b \NR
             \NC d + c - b = \NC a \NR
         \stopalign
     }
\stopformula

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\stoptext

i'll sort out spacing later
