Movies = x
Video Games = y
1st Month = 5x+3y = 26 (1)
2nd Month = 7x+9y = 64 (2)
(1) x 3; 15x+9y = 78 (3)
(3)-(2);
15x+9y-(7x+9y) = 78-64
15x+9y-7x-9y = 14
8x = 14
x = $1.75
Therefore substituting x in (1);
5x1.75+3y = 26
8.75+3y = 26
3y = 26-8.75
y = $5.75
Hope i helped! Please mark Brainliest if you can :)
