A pizza place near your office has small cheese pizzas for $4 and small pepperoni pizzas for $5. You are going to pick up pizzas for fourteen people in your office. You received $65 but forgot how many of each type of pizza you were supposed to pick up.

First set up two equations: 4c+5p=65. C+p=14. Solve one equation and sub it in for the other: C=14-p: 4(14-p)+5p=65, 56-4p+5p=65, p=9. Sub in what you now know: c+9=14, c=5. Check both equations to make sure it's right and you get: Pepperoni=9 cheese=5 :) hope this helps!
