The first thing we must do for this case is to define variables:
 x = rental cost of movies
 y = rental cost of video games
 We write the system of equations:
 6x + 2y = 36
 3x + 5y = 39
 Resolving we have:
 x = 4.25 $
 y = 5.25 $
 Answer:
 The rental cost for each movie and each video game is:
 movies = 4.25 $
 video games = 5.25 $
