Create a function to return the residual:

  function z = f (x)
    z = [(12-x(1))^2+x(2)^2-15^2, (16+x(2))^2+x(1)^2-25^2];
  endfunction

and fsolve it:

octave> fsolve ("f", [0, 0])
ans =

   1.8887e-15
   9.0000e+00


and:

octave:5> fsolve ("f", [24, -9])
ans =

   24
   -9

:)

and so forth :)
