Answer 1

12 m..........2 vg............29$
3m..............5 vg.............32$        | *4

12 m.......2v.g..........29$
12m........20v. g. .....128$
---------------------------------
/            20 v.g - 2 v.g......128-29=99 $
18 v.g......99 $
v.g = 99/18
v.g= 5,5 $

12 m ....2vg....29 $
12m........2*5/5 $.....29 $
12m+11$=29 $
12m=29-11$
12m=18 $
m=18/12$
m=1,5 $
Answer is : 1 movie=1,5 $ and 1 video game =5,5 $
