Question

A dealership sells cars and motorcycles there are a total of 140 vehicles on the lot and they have a total of 370 wheels how many cars and motorcycles are at the dealership?

Answer 1

Below in bold.

Explanation:

As we all know a car has 4 wheels and a motorcycle has 2 so we can write 2 equations:

x + y = 140 where x = number of cars and y = number of cycles.

4x + 2y = 370.............A

Multiply first equation by 2:-

2x + 2y = 280.............B

Subtract equation B from A:

2x = 90

x = 45.

So there are 45 cars and 140 - 45 = 95 motorcycles.
