It is 65...(some) is = x

x - 19 + 17 = 63

65 ....but really though, it is zero since it says "to begin with"...

These brain teasers have always been dumb to me.

If you do it in the order it's written:

X - 19 + 17 = 63
X - 2 = 63
X = 65

Weird though because if you do the problem backwards:

Now there are 63 people on the train
17 people get on
19 people get off

63 + 17 - 19 = 61

whats weird about that

in the first equation you had +19 and negative 17

second you had +17 and negative 19

they are not the same
