Answer:
-3<=a
Explanation:
1. Get the -6 away, so multiply everything by -6. 6*-6 >= -6*-6(a+2)
2. This becomes -1 <= a+2 Since if you multiply or divide anything by a negative number, you have to reverse the inequality sign.
3. Subtract 2 to get a by itself -1-2 >= a
4. This becomes -3 >= a which is the right answer.
(Just so you know >= and <= means less than or equal to and more than or equal to.)
