Thank you for the opportunity to help you with your question!

the first A is -9 and the second A is 9

illustration:

4x+6 < -3

4x<-3-6

4x < -9

case two comes when you multiply either side a negative integer

like in our case if we multiply each side by -1

we get -4x > 9 

thus  A can be -9 or 9


in case of any explanations let me know

Please let me know if you need any clarification. I'm always happy to answer your questions.
