I don't have matlab, but I would assume there is a Solve command similar to
the following.
Are you looking for a more general form of the equation in order to solve
other equations with different variables?

equ =
{
(12-x)^2 + y^2==15^2,
(16+y)^2 + x^2==25^2
};

Solve[equ]

{x -> 0, y -> 9},
{x -> 24, y -> -9}
