I buy 4 hamburgers and 3 sodas and it coast me $30. my brother buys 2 hamburgers and 2sodas and it coast him $16. what is the coast of each hamburger and each soda

Answer:hamburger is 6$

soda is 2$

Step-by-step explanation:

suppose

hamburger=x

soda=y

4x+3y=30 ... (1')

2x+2y=16 ... (2)

multiply 2 to 2 no and do subtraction from 1 no to 2 no

4x+3y=30

4x+4y=32

(-) (-) (-)

-y=-2

y=2

place y=2 to 2 no

2x+2y=16

2 (x+y) = 16

x+y=16:2

x+2=8

x=8-2

x=6
