A student showed work to solve the equation 6(3d +1) – 40 = 9d +8 for d.
6(3d + 1) – 40 = 9d + 8
Step One 18d + 6 – 40 = 9d + 8
Step Two 18d – 46 = 9d + 8
Step Three 9d – 46 = 8
Step Four 9d = 54
Step Five d = 6
The student made a mistake in Step Two. Choose the correct equation for Step Two.
–16d = 17d
24d – 40 = 9d + 8
18d – 34 = 9d + 8
18d + 46 = 9d + 8
