Answer:
Let's denote:
The cost of buying 1 burger: x
The cost of buying 1 drink: y
Then, we have:
5x + 3y = 13 (1)
3x + 5y = 11 (2)
Add up both sides of (1) and (2):
=> 8x + 8y = 24
=> x + y =3 (*)
Subtract both sides of (1) to (2):
2x - 2y = 2
=> x - y = 1 (**)
From (*) and (**):
x = 2
y = 1
=> The cost of buying 2 burgers and 2 drinks: 2(x + y) = 2(2 + 1) = 6$
