Let x be the number of movies rented 
Let y be the number of video games rented 

(5x+2y=26)4
- 3x+8y=53 

 20x+8y=104 
-3x+8y=53
-----------------
17x       =51 
x=51/17 
x=3 

5x+2y=26 
5(3)+2y=26 
2y=26-15 
y=11/2 
y=5.5 

Therefore, the movies cost $3 and the video games cost $5.5 

Hope I helped :)
