Before going to the question, let's review what range is:
Range is the difference between the greatest number and the least number in a data set. Finding range is pretty easy. All you need to do is find the greatest number and lowest number, and find the difference.
In this data set, you have the following numbers:
The greatest number is 11. The lowest number is 2. That means that the range is equal to:
Subtract:
★ The range is 9 ; range = 9

1. We need to get rid of those pesky parentheses. We do this by distributing the 3.
2. We need to get "n" by itself, so we add 9 to both sides.
3. Add like terms.
4. Now, we need to get rid of the -9, so we divide both sides by -9. Remember that dividing by negative numbers changes the direction of the "greater than or equal to" symbol.
5. We divide, and the negatives cancel.
I wrote the answer both ways so that I could tell what the number line needed to look like.
