Let the number of pizza C be x and the number of pizza S be y. We need to obtain two equations in two variables and then solve them to find x and y.

As the total number of pizzas is 85, so

Solve the equation

Now, substitute

Now, substitute

Therefore, the number of pizza C are 50 and the number of pizza S are 35.
