Movie $3.00
Video game: $5.50
Explanation:
Call x the rental cost for one movie
Call y the rental cost for one video
We have two equations:
3x + 8y = 53 (1)
5x + 2y = 26 (2)
Multiply (2) by (-4), then add up the 2 equations
3x + 8y = 53
-20x - 8y = -104
-17x = -51 --> x = $3
Replace x = 3 into (1):
9 + 8y = 53
8y = 44
