What does the graph of 4 < n + 6 < 9 look like?

When an operation is performed in one side of an inequality, that same operation must be done with the other sides. The first step is to subtract 6 from each side.

4 - 6 < n +6 - 6 < 9 - 6

The simplified result is:

-2 <n < 3

Utilize a number line for graphing. Create open circles for -2 and 3 since these are the endpoints of the graph. Lastly, draw a line from -2 to 3.
