Step-by-step explanation:

what do you need to find ?

the number of pizzas and calzones they were eating ?

if so :

p = number of pizzas

c = number of calzones

3p + 2c = 18

2p + 5c = 23

let's multiply the first equation by 2 and the second squadron by 3, and then subtract the second from the first :

6p + 4c = 36

- 6p + 15c = 69

-------------------------

0 -11c = - 33

c = 3

2p + 5c = 23

2p + 5×3 = 23

2p + 15 = 23

2p = 8

p = 4

so, they were eating 4 pizzas and 3 calzones.
