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!
