PLEASE HELP ME
giải hpt:
\(\left\{{}\begin{matrix}\frac{5}{\sqrt{x-1}}-3\left|y+1\right|=-4\\\frac{2}{\sqrt{x-1}}+\left|y+1\right|=5\end{matrix}\right.\)
\(\left\{{}\begin{matrix}\frac{2}{x-2}+3\sqrt{y+1}=4\\\frac{4}{x-2}-\sqrt{y+1}=1\end{matrix}\right.\) tìm đk rồi giải hpt hộ mình nha
Giải hệ phương trình :
a, \(\left\{{}\begin{matrix}2x-\frac{1}{y}=2y-\frac{1}{x}\\2\left(2x^2+y^2\right)+4\left(x-y\right)=7xy-8\end{matrix}\right.\)
b, \(\left\{{}\begin{matrix}2x^3-5y=2y^3-5x\\\frac{3y}{x^2+y+1}+\frac{5x}{\left(y+1\right)^2+x}=x-y+2\end{matrix}\right.\)
(Mong mọi người giúp đỡ! Tick cho mọi người nha !)
\(\left\{{}\begin{matrix}\frac{2x+3}{x+1}+\frac{4}{\sqrt{y}-2}=4\\\frac{5}{x+1}-\frac{2}{\sqrt{y}-2}=4\end{matrix}\right.\)
\(\left\{{}\begin{matrix}\frac{1}{x}+\frac{3}{y-2}=4\\\frac{4}{x}+\frac{1}{y-2}=1\end{matrix}\right.\)
