Because you want to read at least 12 books, the inequality symbol will be less than or equal to (≤).

You can make the inequality be:

12 ≤ 3x

To solve this inequality divide both sides by 3 to isolate x. And you should get:

12 / 3 ≤ 3x / 3

4 ≤ x

... meaning that you will need to read at least 4 books per month to reach the goal.
