Question

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

Answer 1

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