You would have to do 18.18 times 10, keep that answer. then you do 18.18 plus 2.18 and get the answer to that and add it together from the answer from the first question (18.18 times 10)
We want to find y from the equation

Multiply each side by (y - 2).

Note that (y-2) in the numerator and denominator cancel out on the left side.
Therefore
3 = 8(y - 2)
3 = 8y - 16
Add 16 to each side.
3 + 16 = 8y - 16 + 16
19 = 8y
Divideach side by 8.
19/8 = y
Answer:
Multiply each coordinate by two; which then becomes
(16,8), (16,12), (20,12), (20,8)
