Giải hệ Pt:

$\sqrt[3]{x^2-1}-\sqrt{x^3-2}+x=0$

Giải HPT: 

$\left\{\begin{matrix} 3y^2+1+2y(x+1)=4y\sqrt{x^2+2y+1}\\ y(y-x)=3-3y \end{matrix}\right.$

Giải HPT: $\left\{\begin{matrix} y=\sqrt{x+2}\\ (2x^3+12)y+13xy^3+\sqrt{2y^4-1}=(\sqrt[3]{(2x+3)y^2+7}-4)y \end{matrix}\right.$

Giải Hpt:

  $\left\{\begin{matrix} \frac{2}{(\sqrt{x}+\sqrt{y})^2}+\frac{1}{x+\sqrt{y(2x-y)}}=\frac{2}{y+\sqrt{x(2x-y)}}\\ 2(y-4)\sqrt{2x-y-3}-(x-6)\sqrt{x+y+1}=3(y-2) \end{matrix}\right.$

Giải hệ Pt sau: 

$\left\{\begin{matrix} (y^3-1)(x+1)+y=(x+1)^4\\ 2\sqrt{\frac{y+x^2}{y+3}}+(y+1)(x-2)+\sqrt{x+1}=\frac{2+\sqrt{x^3+x^2+x+1}}{\sqrt{x^2+1}} \end{matrix}\right.$
