Tickets to a fundraiser are $14 if purchased ahead of time and $25 if purchase at the door. The total raised from all ticket sales was $625. If eleven tickets were purchased at the door, how many tickets were purchased ahead of time?

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.

Ifigured it out from watching a khan academy video , i am so sorry about the first answer. but i agree that x= 72. and now you can give the other person brainliest if you want.
