Understand that every time you switch a car to a motorcycle, there will be a decrease of 2 wheels in total number of wheels (as reflected in finding difference in wheels for cars and motorcycles).
With 100/2=50, you know that you need to "switch out" a car to a motorcycle 50 times in order to make the total wheels 620.
Therefore, there are 50 motorcycles.
