Question

There is a total of 42 wheels for the bicycles and tricycles in this shop. A bicycle has 2 wheels and a tricycle has 3 wheels, How many tricycles and bicycles are in the shop?

Answer 1

2b +3t =42

1) Gathering the data

42 wheels

Bicycle 2 wheels (b)

Tricycle 3 wheels (t)

2) To find that out, let's write the following linear equation in the standard form to represent that:

2b +3t =42

Note that this linear equation is relating the wheels in total with each one contribution.
