Details: Cargo ship can carry 21,600 tons Cars weigh 3.6 tons each Trucks weigh 7.5 tons each y = number of cars x= number of trucks Your equation was 3.6y + 7.5x = 21600 Find the number of trucks that can be shipped if there are no cars.

Given:

The equation is

where, y is the number of cars and x is the number of trucks shipped.

To find:

The number of trucks that can be shipped if there are no cars.

Solution:

We have,

If there are no cars in the cargo ship, then y = 0 because y is the number of cars.

Putting y=0 in the given equation, we get

Divide both sides by 7.5.

x is the number of trucks shipped.

Therefore, the number of trucks that can be shipped if there are no cars is 2880.
