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.

Answer:
The boats are far apart by 4506.1 feet
Step-by-step explanation:
from the graph attached
i) BC = 1353 
= 2761.82 feet
ii) BD = 1353 
= 1744.28 feet
iii) the boats are far apart by = CD = CB + BD = 2761.82 + 1744.28 = 4506.1 feet
