There are three equations, which one do you want to refer using 
eq:twosolve? You need to refer each equation explicitly. Something 
like
\placeformula \startformula \startalign[m=3]
  \NC 3 -2x \NC> -1 \NC\NC \qor \NC 3-2x \NC 1 \NR[eq:twosolve]
  \NC -2x \NC -4 \NC\NC\NC -2x \NC< -2 \NR
\stopalign \stopformula

Also note that if you use ams style &.. \\ you need to put \\ on the 
last one also.
