$\begin{cases}\dfrac{96}{x+y}+\dfrac{96}{x-y}=14 \\\dfrac{96}{x+y}+\dfrac{72}{x-y}=\dfrac{24}{y} \end{cases}$
Giai chi tiết nha!!!!!!!!!!!!!!
\(\left\{{}\begin{matrix}\dfrac{120}{x}=\dfrac{80}{y}\\\dfrac{96}{x}+1=\dfrac{104}{y}\end{matrix}\right.\) giải hệ
\(\dfrac{72}{x}+\dfrac{54}{y}=6\)
x-y=6

\(\dfrac{1}{x}+\dfrac{1}{y}=\dfrac{1}{16}\)
\(\dfrac{3}{x}+\dfrac{6}{y}=\dfrac{1}{4}\)
Giải hệ PT:\(\left\{{}\begin{matrix}\dfrac{4}{\sqrt[]{2x-y}}-\dfrac{21}{x+y}=\dfrac{1}{2}\\\dfrac{3}{\sqrt{2x-y}}+\dfrac{7-x-y}{x+y}=1\end{matrix}\right.\)
giải hệ pt :
\(\dfrac{5}{x}+\dfrac{3}{y}=1\)
\(\dfrac{2}{x}+\dfrac{1}{y}=-1\)
giải hệ: \(\left\{{}\begin{matrix}\dfrac{1}{x-y}+\dfrac{1}{x+y}=2\\\dfrac{2}{x+y}+\dfrac{3}{x+y}=5\end{matrix}\right.\)
giải pt: \(\sqrt{x^2-4x+7}=\sqrt{x+1}\)
y-\(\dfrac{2}{5}\)=\(\dfrac{x}{50}\)
y+1=\(\dfrac{x}{40}\)
giải hệ pt hộ em vs ạ
Giải hệ pt: \(\left\{{}\begin{matrix}\dfrac{1}{x^2}+\dfrac{1}{y^2}=3+x^2y^2\\\dfrac{1}{x^3}+\dfrac{1}{y^3}+3=x^3y^3\end{matrix}\right.\)
