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
  (-)  (-)   (-) Â
    -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
