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.
