Question

18-6a=4a-4(a+3)

Answer 1

First you have to distribute. So re-write:
18-6a= 4a-(4xa)+(4x3)
18-6a=4a-4a+12=
18-6a=12 (Where did the two 4a's go? Remember 4a-4a=0, so just drop down 12)
(Not done yet...)

Answer 2

diistribute the -4:\[18-6a=4a-4a-12\]combine like terms:\[18-6a=-12\]subtract 18 from both sides:\[-6a=-30\]divid both sides by -6:\[a=5\]
