There are 36 seat and 42 seat buses for a second grade autumn outing in Hangzhou. If there are several 36 seat buses, they are just full. If only 42 seat buses are rented, one less bus can be rented, and a number of buses are not full, but there are more than 30 people How many people go on spring outings in the second year of junior high school? Please use the equation of first degree with one variable,

There are 36 seat and 42 seat buses for a second grade autumn outing in Hangzhou. If there are several 36 seat buses, they are just full. If only 42 seat buses are rented, one less bus can be rented, and a number of buses are not full, but there are more than 30 people How many people go on spring outings in the second year of junior high school? Please use the equation of first degree with one variable,

Set up and rent 36 seat bus x
Then 36x = (X-2) * 42 + 30
The solution is x = 8
Number of people = 36 * 8 = 288
(there is something wrong with the title. There should be a car that is not full and there are only 30 people.)

For autumn outing of a certain grade in a school, if a number of 48 seat buses are rented, it will be full; if a number of 64 seat buses are rented, it will be able to rent one less, and there is one car that is not full, but it will be full
More than half. (1) how many buses need to be rented?
(2) If it costs 250 yuan for each 48 seat bus and 300 yuan for each 64 seat bus, which bus is more cost-effective?

1. Let 48 seat cars be x cars and 64 seat cars be y cars
48x=64y-31 (1)
x-1=y (2)
Formula (2) is substituted by (1) to obtain: 48x = 64 (x-1) - 31 (3)
Simplified formula (3), 48x = 64x-64-31 (4)
That is, x = (64 + 31) / (64-48)
=95÷16
≈6
y=x-1
=6-1
=5.
2. A 48 seat car costs 250x6 = 1500 yuan;
A 64 seat car costs 300 x 5 = 1500 yuan
A: you need to rent 6 cars with 48 seats and 5 cars with 64 seats. The rent for both cars is 1500 yuan, and the cost is the same
Hope to help you!

30 tons of fish are stored in warehouse A, 40 tons are transported to warehouse B, and 80 tons are transported to warehouse A and warehouse B, so that warehouse A is 1.5 times of warehouse B. how many tons are transported by warehouse A and warehouse B respectively
Please list the equation

A x tons, B (80-x) tons,
30+X=[40+(80-X)]*1.5

6、 In a fish farm, 30 tons of fish are stored in warehouse A and 40 tons are stored in warehouse B. now 80 tons of fish are transported to these two warehouses
6、 Solving practical problems with equations (8 points)
28. In a fish farm, 30 tons of fish are stored in warehouse A and 40 tons are stored in warehouse B. now they are to be transported to these two warehouses
Send 80 tons of fish, so that the amount of fish in warehouse A is 1.5 times of that in warehouse B
How many tons of fish don't you ship?

If x tons of fish should be transported to warehouse A, then (80-x) tons of fish should be transported to warehouse B
30+x=1.5×[（80-x）+40]
30+x=180-1.5x
2.5x=150
x=60
80-x=80-60=20
A: 60 tons and 20 tons of fish should be transported to warehouse A and warehouse B respectively
