Need help problem solving--

A 500 space parking lot is packed with motorcycles and passenger cars, with only one vehicle in each space. How many motorcycles & cars r there if the total number of tires on the parked vehicles is 1650?

I think I have to do this in some kind of equation format, I am so confused.

x = number of cars
y = number of motorcycles
4x = number of tires for cars
2y = number of tires for motorcycles

x + y = 500
4x + 2y = 1650

solve together

you should get
325 cars
175 motorcycles
