There are 6 skateboards and 15 bicycles.

Step-by-step explanation:

Consider the provided information.

Let x is the number of skateboards and y is the number of bicycles in his repair shop.

Uncle Eddie asked McKenna and Lara to order 54 new wheels for the 21 skateboards and bicycles in his repair shop.

There are 21 skateboards and bicycles in his repair shop.

......(1)

Each skateboard has 4 wheels, for x skateboards he needs 4x wheels, each bicycle has 2 wheels, for  y bicycles he needs 2y wheels. In total there should be ordered 54 wheels, so

Substitute the value of x in above equation.

Substitute the value of y in equation 1.

Hence, there are 6 skateboards and 15 bicycles.
