For the given circle, which of the following is true regarding its circumference and area?
OA
The circumference is larger, and it is four times the area.
OB
The area is larger, and it is four times the circumference.
OC
The circumference is larger, and it is two times the area.
OD.
The area is larger, and it is two times the circumference,

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
