Problem

Suppose $\displaystyle \frac{1}{20}$ is either x or y in the following system:

$\begin{cases} xy=\frac{1}{k}\\ x=ky \end{cases}$

Find the possible values of k.

Solution

This problem needs a solution. If you have a solution for it, please help us out by adding it.

if $x=\frac{1} {20}$, then $\frac{y} {20} = \frac{1} {k}$ and $ky=20$
