Let's solve the first inequality :

Start with the first inequality.

Add to both sides.

Combine like terms on the right side.

Divide both sides by to isolate .

Now let's solve the second inequality :

Start with the second inequality.

Add to both sides.

Combine like terms on the right side.

So our answer is or

So the solution in interval notation is: (

]

[

)

Also, the solution in set notation is:

Here's the graph of the solution set

Note:
There is a closed circle at which means that we're including that value from the solution set.
