Not exactly. In this, I get two formula numbers, one for the case 
`x=7' and the other for the entire equation. I can remove 
\placeformula and almost get the desired behaviour. There should be an 
option to flushright the equation number corresponding to each case, 
i.e., I should be able to get

Where the frame is the page boundaries. I hope I am making sense here.

Further, I can not get correct subnumbering here. Look at the output 
of

\startformula \startcases
\NC a \NC if something \NR[eq:a][a]
\NC b \NC otherwise    \NR[eq:b][b]
\stopcases \stopformula

Other than these minor glitches, this is perfect.
