Answer 1

is anyone able to help with this one?

Answer 2

[3(6-2a)+a-3] is this all a numerator?

Answer 3

yes it is

Answer 4

are sure about all signs of numerator and denomenator?

Answer 5

numerators are 3(6-2a)+a-3
denomenators are 9-3a

Answer 6

= ( 18-6a+a-3)/(9-3a) = (15-5a)/(9-3a) = 5( 3-a)/3(3-a) = 5/3

Answer 7

expand the numerator then take a common factor of 5 in numerator and a common factor of 4 denomenator, you cancel to ger 5/3 , hope that helps.
