. And then simplify, and it gave us, 
. Divide by 7 from both sides of equation, and it gave us, 
. Finally simplify, and it gave us the answer is a=-1+b/7 is the right answer. 
. And then simplify, and it gave us, 
. Next you can also divide by -4 from both sides of equation, and it gave us, 
. Finally simplify, and it gave us the answer is a=-b-1/2 is the right answer. Hope this helps! And thank you for posting your question at here on , and have a great day. -Charlie
