Answer: x = 6, y = 4

Step-by-step explanation:

Soda = $2 per bottle

Chips = $3 per bag

x- no of bottles of soda

y- no of bags of chips

x + y = 10

2x + 3y = 24

x = 10 - y

2x + 3y = 24

2(10 - y) + 3y = 24

20 - 2y + 3y = 24

Collect like terms

-2y + 3y = 24 - 20

y = 4

x = 10 - y

x = 10 - 4

x = 6
