Answer 1

if you're just looking for if your work is right it is so far! :)

Answer 2

is it completely simplified though?

Answer 3

after you just combine like terms on the left, then subtract =a+30b to the left! :)

Answer 4

so you would get 9a-8a+= a
then 18b+12b= 30b

so you have a+30b=a+30b

subtract right side to the left side and your answer is gonna be 0!
