Question

You rent 2 DVDs and 1 video game for $12. The following week, your friend rents 4 DVDs and two video games for $24. Which of the following statements apply? One solution, no solution, infinitely many solutions, the video game cost more than dvd rentals or you cannot determine the costs of dvd or video game rentals.

Answer 1

There are inifinite solutions because they are the same equation

2D + 1G = 12

and

4D + 2G = 24 (divide by 2) 2D + G = 12

2D + 1G = 12 is the same as 2D + 1G = 12
