Answer 2

A car has 4 wheels.  A motorcycle has 2 wheels.  Both the cars and motorcycles are vehicles.  Use this additional information as well as the info in your problem to write two equations.

 

One equation will represent the total number of vehicles.  The other equation will represent the total number of wheels.
