Step 1: Subtract
from both sides. Leaving us with 
Step 2: Add
to both sides. Leaving us with 
So, your answer would be y = -3x
1, when you factor you get 6x(x^2-1)+4(x^2-1)=
Divide both sides by 5 and then n + 2 =2 so the answer is n=0
hope this help
C, both numbers form a mostly linear relationship.
