rents a bike with safety equipment for $5 a day. if you provide your own safety equipment, the
bike rental is $3 a day. you could buy the equipment at a sports store for $28. how many times

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
