Answer:
b=9a+4
Step-by-step explanation: First you have to distribute -3(b-6) which gives you -3b+18. Then you have 27a-3b+18=6. Then you do 6-18 which gives you -12. Simplifying again you have 27a-3b=-12. Next, you have to subtract 27a from 27a-3b and it gives you -3b=-27a-12. Then divide -3 from both sides which then gives you b=9a+4
