Who /dumb/ here?The answer is not 61 dumb fuck.
>>28462421
let the starting number of people = x
x -19 + 17 = 63
x -2 = 63
x = 65
65 people were on the train to begin with
>61
19 - 100 ( could use any number here ) = 81
81 + 17 = 98
98 - 63 = 35 people on the train
simple
It's 65
oreeeeeeeeegano

How did you come up with this weird, convoluted method? Who taught you to do this? Were you homeschooled? Let me show you an easier way. Let x = the amount of people who were on the train to begin with and write:
x - 19 + 17 = 63

Was the movie 'A Beautiful Mind', based on you?
>>28462421
Doesn't "to begin with" imply a number before the first stop?

>autistic people think this post is serious
too many keks
>>28462421
huh
63 - 17 = 46
46 + 19 = 65
i'm a fucking retard, how does anyone get '61'?
>>28462590
check muh work
19 - 17 = 2
63 + 2 = 65
yay i'm as smart as an 8 year old
>>28462451
Thats all well and good if you remember the forumla.
>>28462572
Really hope you are joking rn
>>28462590
You start with x, the total amount of people..
19 people leave, so you get x - 19. 17 people get on, however, so you actually get x - 19 + 17, and since we know how many people are on the train after that, we can say that x - 19 + 17 = 63. If you do the math on the non-x numbers, you get x - 2 = 63. If you add 2, you get x, which is 65. But, if you just subtract the 2, you get 61. So, I assume that's what people get wrong.

That isnt a memorized forumla for this quetion, it is literally just finding x, it can be used to find unknown values. Did you not take grade 7 math?
>>28462459
How did you even fuck up this badly

This is /r9k/. Everyone on here is an idiot who thinks he's a genius.
