Sagot :

Answer:

Below in bold.

Step-by-step 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.
