Answer:
Step-by-step explanation:
There are 18 vehicles in a garage. Some are cars and others are bicycles. there are 50 wheels all together. how many cars and bicycles are there.
A car has 4 wheels
A bike has 2 wheels
c = number of cars
b = number of bikes
There are a total of 18 vehicle, which has 50 wheels altogether.
Our system of equations are:
c + b = 18
4c + 2b = 50
c + b = 18
- b - d
c = -b + 18
4(-d + 18) + 2d = 50
-4d + 72 + 2d = 50
-2d + 72 = 50
- 72 - 72
-2d = -22
-2 /-2
b = 11 bikes
c + b = 18
c + 11 = 18
- 11 - 11
c = 7 cars
Therefore, there are 7 cars and 11 bikes.
Hope this helps!
