Ta có : x.y=10

\(\Rightarrow x.y=2.5\)

\(\frac{\Rightarrow y}{5}=\frac{2}{x}\)

Mà x/2 = y/5

\(\frac{\Rightarrow x}{2}=\frac{2}{x}\)\(\Rightarrow x.x=2.2=4\)

\(\Rightarrow x^2=4=2^2=\left(-2\right)^2\)

\(\Rightarrow x=2\)hoặc \(x=-2\)

Khi \(x=2\)thì y=10 :2 =5

Khi x=-2 thì y=10: -2=-5

Vậy:   \(\hept{\begin{cases}x=2\\y=5\end{cases}}\)hoặc\(\hept{\begin{cases}x=-2\\y=-5\end{cases}}\)
