The given equation is


u=y+(k)/(x)

First, let's subtract y from each side.


\begin{gathered} u-y=y-y+(k)/(x) \\ u-y=(k)/(x) \end{gathered}

Then, we multiply x on each side.


\begin{gathered} x(u-y)=x\cdot(k)/(x) \\ x(u-y)=k \end{gathered}

At last, let's divide each side by u-y.


\begin{gathered} (x(u-y))/(u-y)=(k)/(u-y) \\ x=(k)/(u-y) \end{gathered}

Therefore, the final expression is


x=(k)/(u-y)
