Let's equate the two given points:

(x + 7, 3) = (5, 6 + y)

This means that the x-coordinates are equal, so:

x + 7 = 5

Now, we can solve for x:

x = 5 - 7

x = -2

Now, let's look at the y-coordinates:

3 = 6 + y

To solve for y:

y = 3 - 6

y = -3

So, the values of x and y are -2 and -3, respectively. Therefore, the correct option is (C) -2, -3.
