Answer:
Step-by-step explanation:
The two purchases can be described by ...
3b +2d = 35
2b +d = 22
Subtracting the first equation from twice the second, we get ...
2(2b +d) -(3b +2d) = 2(22) -(35)
b = 9 . . . . . . . . simplify
Then ...
2(9) +d = 22
d = 4 . . . . . . . . . subtract 18
A burger costs $9 and a drink costs $4.
