Let x be the number of people on the train.

x - 19 + 17 = 63

x = 65

There were 65 people on the train.

63-17+19 = 65 <<<

To check: 65-19 = 46

46 + 17 = 63

At start, x were on the train. Then 19 got of leaving x-19 on the train. Then 17

got on, leaving x-2 = 63 on the train. So x = 65.

If 19 people got off but then 17 people got on, that's the same as if only 2 people got off.

Add back the 2 people and you have 65 that were on the train to begin with.

65

N +19 – 17 = 63

N = 63 + 17 – 19 = 63 – 2 = 61
