Interval Notation

First, let’s solve the inequalities!

For :
Adding 7 to both sides gives . Now, divide by -2 (don’t forget to flip the inequality):
.

Now for :
Adding 2 to both sides gives .

Now we combine these findings. The first inequality indicates all numbers less than -4, and the second one indicates all numbers greater than or equal to 1. Thus, the solution in interval notation is:
