Réitigh do y,x. (complex solution)
x=-\left(-2^{e+1}\left(e-1\right)-i\sqrt{\pi -2}+1\right)\approx 21.615633627+1.068453393i\text{, }y=-i\sqrt{\pi -2}+1\approx 1-1.068453393i
x=-\left(-2^{e+1}\left(e-1\right)+1+i\sqrt{\pi -2}\right)\approx 21.615633627-1.068453393i\text{, }y=1+i\sqrt{\pi -2}\approx 1+1.068453393i
