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
<u> (-) (-) (-) </u>
-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
