Mattie ordered 51 vegetable pizzas and pepperoni pizzas for the eighth-grade party. The number of vegetable pizzas, v, was 3 more than 5 times the number of pepperoni pizzas, p. How many pepperoni pizzas did she order?

We can form an equation for the relationship between vegetable pizzas and pepperoni pizzas.

v=5p+3.

 

The total number of pizzas is v+p=51. Substitue 5p+3 for v and solve for p.

 

(5p+3)+p=51

6p+3=51

6p=48

p=8 pepperoni pizzas.
