You can put this solution on YOUR website!
You subtracted 1 from the middle, so you need to do that to the left and right sides.

On the left, you'll get -53 - 1 = -54 (not -52)

On the right, you'll get -26 - 1 = -27


So you should have -54 < 9v < -27

From here, divide all sides by 9 to get


-54/9 < 9v/9 < -27/9

-6 < v < -3

which is the answer.
