5m+3v=25

2m+6v=40

10m+6v=50

8m=10>>m=1.25

1.25*5=6.25

25-6.25=18.75

3v=18.75>>v=6.25

5*1.25+3*6.25=25

2*1.25+6*6.25=40

m=1.25, V=6.25

let x - cost of movies

y - cost of video games

3[2x + 6y = 40]

6[5x + 3y = 25]

----------------------

6x + 18y = 120

-[30x + 18y = 150]

--------------------------

..- 24x = - 30

x = $1.25 cost of movies

solving for y from eq1

2x + 6y = 40

2(1.25) + 6y = 40

2.5 + 6y = 40

6y = 40 - 2.5

6y =37.5

y = $6.25 cost of video game

Rental cost for each movie: $1.25

Rental cost for each video game: $6.25
