Dear Aditya, Otared, and Hans,
Hello,
Thank you all very much for your help. Your codes work fine. However when I use
\setupformulas[location=right] the equation numbers apperar on the rightmost of
the line, but with \setupformulas[location=left] the equation numbers
appear near
the formulas

Hi Mingranina,
For displayed aligned formulas it is better to use \startalignâ€¦\stopalign,
instead of the plain TeX construction \leqalignno.
indeed, and at some point they might even get nilled .. we can't use
them in complex cases anyway

Please have a look at the following:

I am trying to compile the following example (from
