Giải thích các bước giải:
\(\left\{\begin{matrix} \frac{1}{x}+\frac{1}{y}=\frac{1}{24}
& & \\ \frac{1}{x}=1,5.\frac{1}{y}
& &
\end{matrix}\right.\)
\( \Leftrightarrow \left\{\begin{matrix} \frac{1}{x}+\frac{1}{y}=\frac{1}{24}
& & \\ 2y=3x
& &
\end{matrix}\right.\)
\( \Leftrightarrow \left\{\begin{matrix} \frac{1}{x}+\frac{1}{y}=\frac{1}{24}
& & \\ y=1,5x
& &
\end{matrix}\right.\)
\( \Leftrightarrow \left\{\begin{matrix} \frac{1,5+1}{1,5x}=\frac{1}{24}
& & \\ y=1,5x
& &
\end{matrix}\right.\)
\( \Leftrightarrow \left\{\begin{matrix} x=40
& & \\ y=1,5x=1,5.40=60
& &
\end{matrix}\right.\)
