Start with the given compound inequality.

Subtract from all sides.

Combine like terms on the left side.

Combine like terms on the right side.

So the answer is

So the answer in interval notation is (

)

Also, the answer in set-builder notation is

Here's the graph of the solution set

Graph of the solution set

Note:
There is an open circle at which means that we're excluding this value from the solution set
