To solve for three variables you need three independent equations that use them.
Let x = the number of small pizzas
Let y = the number of medium pizzas
Let z = the number of large pizzas
Eq (1) x + y + x = 20
Eq (2) 5x + 9y + 12z = 181
Eq (3) 3x + 4y + 5z = 82
That'll get you halfway there. Good luck.
By the way, Blessed is right. Story problems are applied math. You need to learn to do this yourself.

h(x) = x + 1; f(x)= x^3 - 4x^2 + 3x + 8
