x + 84248 = 105000
$$x + 84248 = 105000$$
     2        
1 - y  = 2 + x
$$1 - y^{2} = x + 2$$
1 - y^2 = x + 2
Rapid solution
$$x_{1} = 20752$$
=
$$20752$$
=
20752

$$y_{1} = - \sqrt{20753} i$$
=
$$- \sqrt{20753} i$$
=
-144.059015684545*i
$$x_{2} = 20752$$
=
$$20752$$
=
20752

$$y_{2} = \sqrt{20753} i$$
=
$$\sqrt{20753} i$$
=
