Let variable for cheesse pizzas be c and for pepperoni pizza be p

3 c + 4 p = 85

2 c + 5 p = 87 

Multiply firsts equation by 2 and second by 3 to equalise the coeficient of one of the variables.

6 c + 8 p = 170 ...............1

6 c + 15 p = 261................2

Subtract equation 1 from 2

7 p = 91

p = 13

Hence, c = 11

Answer, $13 was he price of  pepperoni pizzas, and $11  was that of cheese pizzas !
