There are 8 bicycles and tricycles on the court. They have a total of 22 wheels.

There are 8 bicycles and tricycles on the court. They have a total of 22 wheels. How many bicycles and tricycles are there on the court?

We solve the problem through the conditional variables “X” and “Y”, which will denote the number of 2-wheeled and 3-wheeled bicycles, respectively.

Then, applying the conditions of the problem, we obtain the following equations:

1) X + Y = 8;

2) 2x + 3U = 22.

Solving a system of 2 equations with 2 unknowns, we get X = 8 – Y.

Substituting X into the second equation, we have 2 x (8 – Y) + 3Y = 22 or 16 – 2Y + 3Y = 22 or Y = 22 – 16 = 6 tricycles.

Therefore, X = 8 – 6 = 2 two-wheeled bicycles.

Answer: there were 2 two-wheeled and 6 tricycles on the site.
