12a= 30 + 2a
12a - 2A = 30
10a = 30
10a /10 = 30 / 10
a = 3

Hi,
Here are the steps you need to follow:
12a = 30 + 2a <-- Your problem
10a = 30 <-- Subtract 2a from both sides of the equation
a = 3 <-- Result after dividing both sides by 10. FINAL ANSWER
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew

12a-2a=30+2a-2a
10a=30
a=3

ok you minus the 2a from both sides and the 12a would becomea 10a then you divide 10 on both sides and yuou get 3. a=3
