The first batch of 360 tons of chemical fertilizer transported to a certain place requires 6 trains plus 15 cars, and the second batch of 440 tons requires 8 trains plus 10 cars. How many tons are loaded into each train skin and each car on average

The first batch of 360 tons of chemical fertilizer transported to a certain place requires 6 trains plus 15 cars, and the second batch of 440 tons requires 8 trains plus 10 cars. How many tons are loaded into each train skin and each car on average

Equations 6x + 15y = 120
8X+10Y=440
The equations are divided into two parts: 2x + 5Y = 120
4X+5Y=220 ②
② The solution is x = 50, y = 4

Three railway cars and five trucks can hold a total of 75 tons of cement, two railway cars and ten trucks can hold a total of 70 tons of cement
How much cement can the car hold?

Three wagons and five trucks can hold 75 tons, while six wagons and ten trucks can hold 150 tons
Two cars can hold 70 tons for 10 trucks, so four cars can hold 80 tons,
One truck can hold 20 tons, and one truck can hold (70-2 * 20) / 10 = 3 tons
So 4 cars and 4 trucks can hold 4 * 20 + 4 * 3 = 92 tons of cement
