1. <u><em>a=-1+b/7 is the right answer.</em></u> First you had to add by b from both sides of equation, and it gave us,
. 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.

2. <em><u>a=-b-1/2 is the right answer.</u></em> First you had to add by 2b from both sides of equation, and it gave us,
. 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 brainly, and have a great day. -Charlie
