Đặt \(\dfrac{x}{4}=\dfrac{y}{7}=k\)

\(\Leftrightarrow\left\{{}\begin{matrix}x=4k\\y=7k\end{matrix}\right.\)

Ta có: xy=112

\(\Leftrightarrow28k^2=112\)

\(\Leftrightarrow k^2=4\)

Trường hợp 1: k=2

\(\Leftrightarrow\left\{{}\begin{matrix}x=4k=4\cdot2=8\\y=7k=7\cdot2=14\end{matrix}\right.\)

Trường hợp 2: x=-2

\(\Leftrightarrow\left\{{}\begin{matrix}x=4k=-8\\y=7k=-14\end{matrix}\right.\)

Lời giải:
Mỗi người mỗi ngày làm được số sản phẩm là:
