You can put this solution on YOUR website!
18-6a=4a-4%28a%2B3%29 use distribution to expand the term in parens on the right side
18+-+6a+=+4a+-4a+-+12 put all the terms with a on one side and all the consants on the other
18%2B+12+=+4a+-+4a+%2B+6a simplify
{{30 = 6a}}} solve for a by dividing both sides by 6
30%2F6+=+a
5+=+a
