Solution: There are X ships.
8(x- 1)=6(x+ 1)
2x= 14
x=7
Therefore, the number of students is: 8×(7- 1)=48 (people).
There are 48 students going boating.
There are x people in the car and 9 people in the van, which is three times less than that in the car. The bus actually carries 43 people, 3 more than the 10 times of the car. Find out the equal relationship between quantity and quantity, and then list the corresponding equations and solve them.
Solution: the equal relationship between quantity and quantity
(1) Passenger capacity relationship between car and van: 3x-3=9.
(2) The relationship between bus and car capacity: 10x+3=43.
(1) The original number of passengers in the car is 3x-3=9.
3x= 12
x=4
(2) The number of passengers in the car is 10x+3=43.
10x=40
x=4
I hope I can help you!
