I will try to solve this problem without using any variable.

Notice that an engineering classroom has #32-24=8# more seats than a typical one. If all 16 classrooms were typical ones, then we would have only #24 times 16=384# seats total, which is #424-384=40# seats short. So, we have to turn #40 divide 8=5# classrooms into engineering ones.

Hence, the wing has 11 typical and 5 engineering classrooms.


I hope that this was helpful.
