n ≥ -7
n ≤ -7
n ≥ -3
n ≤ -3

3*(n+5) >= -6 =>
3n+15 >= -6
3n+21 >= 0
n >= -21/3
n >= -7
answer A.

As long as you don't multiply or divide by a negative number, you can solve these as if they are equations. If you do multiply/divide by a negative, greater thans turn in to smaller thans and vice-versa.
