Question

Casey orders 3 pizzas and 2 orders of breadsticks for a total of 30.00. Rachel orders 2 pizzas and 3 orders of breadsticks for 25.00. How much does pizza cost

Answer 1

8

Explanation:

x=pizza

y= breadsticks

3x+2y=30

2x+3y=25

first we myltiply the top equation with 3 and then w emultiply the lower equation with -2 so it is

9x+6y=90

-4x-6y= -50

now we can add them together and the y contracts

5x=40

now we divide it by 5

x=8

So pizza costs 8
