lunches and the same number of desserts.

ordered?
what the x and y value.

Answer 1

no. who eat lunch special = 12

no. who eat dessert = 6

Explanation:

Let x = no. who eat lunch special

y = no. who eat dessert

(1) 8x + 2y = 108 (2) 6x + 3y = 90

Divide thru by 2 Divide thru by 3

4x + y = 54 2x + y = 30

-2x - y = -30

2x = 24

x = 12 2(12) + y = 30

24 + y = 30

y = 6
