Give me the equation of each circle

Q1:
(x + 3)2 + y2 = 16
Q2:
x2 + (y + 3)2 = 4

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
