Đề bằng LaTex:
Giải hệ phương trình:$\left\{\begin{matrix}\frac{x+y}{xy}+\frac{xy}{x+y}=a+\frac{1}{a} \\ \frac{x-y}{xy}+\frac{xy}{x-y}=c+\frac{1}{c} \end{matrix}\right.$
Với $a,c\neq 0$
Treasure every moment that you have!
And remember that Time waits for no one.
Yesterday is history. Tomorrow is a mystery.
Today is a gift. That’s why it’s called the present.
