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

you multiply first the two members of the equation by -1 so you get 

6=a-3 then you can add 3 on the two members you get 6+3=a-3+3 so finally a =9


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