-2x+y=5
x-3y=-30 so you can multiply the bottom equation by 2 you'll get 2x-6y=-60
-2x+y=5
2x-6y=-60 And subtract the equations. You'll get -5y=-55 y=11. Plug it in to one of the original equations. -2x+(11)=5
-2x=-6 so x=3
y=11 and x=3
Unbelievably the same answer! Why? circumference is r * 2 * 3.14 = C
so i divided 12.56 with 3.14 = 4 / 2 = 2
the area of circle r^2 * 3.14 = A
2*2 = 4 * 3.14 is the same as circumference
The answer is -(3x+1)(x+5)
