Giải hệ phương trình:
\(\hept{\begin{cases}\frac{x+\sqrt{x^2-y^2}}{x-\sqrt{x^2-y^2}}=\frac{9x}{5}\left(1\right)\\\frac{x}{y}=\frac{5+3x}{6\left(5-y\right)}\left(2\right)\end{cases}}\)
Giải hệ phương trình sau:
\(\hept{\begin{cases}\left(9x^2+2\right)x+\left(y-2\right)\sqrt{4-3y}=0\\9x^2+y^2+\frac{4}{3}\sqrt{2-3x}=\frac{10}{3}\end{cases}}\)
\(x^2+\frac{9x^2}{\left(x+3\right)^2}=27\)
\(x^2+\frac{9x^2}{\left(x+3\right)^2}=27\)
