at a concession stand three hot dogs until hamburgers cause a 52 hot dogs and three hamburgers cost $9. find the cost of one hot dog and the costume one hammer

Answer 1

3 x + 2y = 5

2 x + 3y = 9

elimination:

2 ( 3x + 2y = 5)

-3(2x + 3y = 9)

6x + 4y = 10

-6x + -9y = -27

-5y = -17

y = -17/-5 = 3.40

2 x + 3(3.40)= 9

2x + 10.20 = 9

2x = -1.20

x = -0.60
