There were some people on a train. 19 people got off the train at the first stop. 17 people get on the train. Now there is 63 pe

maria [59]

Answer:

65 people.

Step-by-step explanation:

We have to work backwards.

We end with 63 people, and at the stop we lost 19 people and gained 17.

$x - 19 + 17 = 63\\$ ; if x = # people at the beginning

$x - 19 + 17 = 63\\x - 2 = 63\\x = 65$

There were 65 people on the train to begin with.
