Welcome.
These is another method to solve this type of questions.
Assumption method, teach on later or P4 or P5. It work this way...

Assumed all are motorcycles, total wheel = 30×2 = 60
Total wheel shortage = 96 -60 =36
Every motorcycle short of 2 wheels compare to car.
Therefore, total car = 36÷2 = 18 cars.
