Answer: Both A, and C

Explanation:

The answer to the first system of equations (2x+2y=16) would be

x=3 and y=5 ( 3x-y=4 )

Which means we have to find out which of the other equations has an x value of 3, and a y value of 5.

If A is 2x+2y=16, then x=3 and y=5

6x-2y=8

If B is x+y=16, then x=5 and y=11

3x-y=4

If C is 2x+2y=16, then x=3 and y=5

6x-2y=8

If D is 6x+6y=48 , then x=-2 and y=10

6x+2y=8

Both A and C are equal to the first system of equations, which means they are both correct answers.
