The issue is that the question doesn't seem to be solved mathematically, as the original poster claims the answer is not 16, when mathematically it should be 16.

3x = 24 <=> x = 8

x + y = 25 <=> y = 17

y + z = 8 <=> z = -9

x+y+z = ? = 16

The answer of 16, suggested as incorrect in the question, is the solution - I entered it into the app and it passed.
