I-solve ang x (complex solution)
\left\{\begin{matrix}x=y+\frac{\sqrt{4y+1}}{2}+\frac{1}{2}\text{, }&arg(\frac{\sqrt{4y+1}+1}{2})<\pi \\x=y-\frac{\sqrt{4y+1}}{2}+\frac{1}{2}\text{, }&y=0\text{ or }arg(\frac{-\sqrt{4y+1}+1}{2})<\pi \end{matrix}\right.
I-solve ang y (complex solution)
y=x-\sqrt{x}
I-solve ang x
