Answer:

Option A.

Explanation:

The given equations are


2y-2x=12 ...(1)


x^2+y^2=36 ...(2)

From equation (1), we get


2y=12+2x


y=(12+2x)/(2)


y=6+x ...(3)

Substitute
y=6+x in equation (2).


x^2+(6+x)^2=36


x^2+36+12x+x^2=36


2x^2+12x=0


2x(x+6)=0


x=0,-6

Put x=0, in equation (3).


y=6+0=6

Put x=-6, in equation (3).


y=6-6=0

It means, (0,6) and (-6,0) are two solutions of the given system of equations.

Therefore, the correct option is A.
