The given equation is


-px+r=-8x-2

First, we add 8x on each side


\begin{gathered} 8x-px+r=-8x+8x-2 \\ x(8-p)+r=-2 \end{gathered}

Then, we subtract r from each side


\begin{gathered} x(8-p)+r-r=-2-r \\ x(8-p)=-2-r \end{gathered}

At last, we divide the equation by 8-p


\begin{gathered} (x(8-p))/(8-p)=(-2-r)/(8-p) \\ x=(-2-r)/(8-p) \end{gathered}

Hence, the answer is


x=(-2-r)/(8-p)
