the math class had 29 enrolled students while 34 students were enrolled into both classes, how many are enrolled in only one of the classes?

Answer 1

how can there be only 29 math students, if 34 are enrolled into both classes? Surely at least 34 were in math.

Plus, since you don't say how many total students there are, there's no way of knowing how many were in only the "other" class.
