i don't understand how you got 63/2. Mr F says: Did you multiply the numbers? . You're meant to do more than just look at the solution - you're meant to mess in and do it yourself, using what I posted as a guide.
and also -3((-3y+9)/2))y equals (9y^2 -27y)/-6y?????? is that correct
Mr F says: Certainly not! Why are you multiplying the bottom by -3 and y as well?? Do you honestly think that something like ? The answer is (9y^2 -27y)/2
