y = 3x - 6
y = x + 10

I decided to rent a PS5 from gamestop for a fee of $50 plus $10 per day. To rent a XBOX one is a $60 plus $5 per day. After how many days will the cost the same?
2 days or x=2
2.4x + 110.5 = .8x + 125.3
x=9.25
y = 4x - 3
y = 2x + 3
(3,9)
2x + 3y = 19
y= 2x + 1
(2,5)
6.6x + 3.4 = 2.1x + 21.4
x=4
