#a > -12#

Explanation:

Multiply everything by 3 to cancel out the division by 3 on the left, and that should leave you with #a > 3 * -4# or #a > -12#.

(Dividing and multiplying are opposites, like adding and subtracting or integrating and differentiating. One does something, the other undoes it. If you want to get rid of a multiplication, divide it. If you want to get rid of an integration, differentiate it.)
