Set a total of X tons of coal
X/(8-2)-X/8=2.5
X/6-X/8=2.5
X/24=2.5
X=60
A total of 60 tons of coal

For a batch of steel, the trolley needs 45 cars to transport, and the cart needs 36 cars to transport. The cart pulls 4 tons more than the trolley each time. How many tons of steel are there in total? (calculation process)

Set trolley, pull x tons per car
45X=36(X+4)
X=16
16 * 45 = 720 tons
