The first step to solving this is to multiply both sides of the equation by 3
8 + 10y = 9y - 12
now move the variable to the left side and change its sign
8 + 10y - 9y = -12
move the constant to the right side and change its sign
10y - 9y = -12 - 8
collect the like terms for y
y = -12 - 8 (it equals 1 when you subtract 10 from 9 which is the same is simply saying "y")
calculate the difference on the other side of the equals sign
y = -20
this means that the correct answer to your question is -20.

What is the question you need answered?!
Answer:
C' = (2, 1)
Step-by-step explanation:
The co-ordinates of C from the graph is: C(6, 3).
When a co-ordinate is dilated by a factor, say 'a' then each term in the co-ordinate is dilated by 'a'.
Therefore, here, we will have: 
(6, 3)
= (2, 1)
Call this C'. Therefore, the co-ordinate of C' = (2, 1).
Hence, the answer.
