A bike rental costs $8 per hour. Desiree has a coupon for 2 free hours. To find how many hours she can rent with $40, Desiree sets up the equation 8(x – 2) = 40, where x is the number of hours.


Drag equations into order show a way to solve for x


8x = 56

8x + 16 = 40

x = 3

8x = 24

x = 7

8x – 16 = 40

8(x – 2) = 40

\(8(x-2)=40 \ \ \ (expand \ the \ brackets) \\ \downarrow \\ 8x-16=40 \ \ \ (add \ 16) \\ \downarrow \\ 8x=56 \ \ \ (divide \ by \ 8) \\ \downarrow \\ x=7\)
