1. Students go boating. If one boat is reduced, each boat can only take eight people. If you add a boat, each boat can take exactly six people. Do you know how many students go boating?

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!
