Chapter 3 - Solving Inequalities - 3-3 Solving Inequalities Using Multiplication or Division - Practice and Problem-Solving Exercises - Page 182: 33

-3, -4, -5, and -6

We need to get the variable alone. In order to cancel out division, we use multiplication, so we multiply both sides of the inequality by 2. Thus, we obtain that $x \leq -2$, so -3, -4, -5, and -6 are solutions to this inequality.
