Find the equation of the circle whose center is the same as the known circle X &; 0 &; 5 + Y &; 0 &; 5-6x + 4y-7 = 0 and passing through point a (2,3)

If the known circle is: x ^ 2 + y ^ 2-6x + 4y-7 = 0, that is: (x-3) ^ 2 + (y + 2) ^ 2 = 20,
The center of the circle is (3, - 2),
r=√[(3-2)^2+(-2-3)^2]=√26,
——》The equation of the circle is: (x-3) ^ 2 + (y + 2) ^ 2 = 26
