    $\displaystyle H=\frac{xW}{x-8s} $

    Multiplying both sides by x -8s we get:

    $\displaystyle H(x-8s)=xW $
    $\displaystyle Hx - 8Hs = xW $

    If we subtract xW from both sides we get all the terms containing x on the left hand side:

    $\displaystyle Hx - xW -8Hs = 0$

    Adding 8Hs to both sides:

    $\displaystyle Hx - xW = 8Hs $

    Factorising the left hand side:

    $\displaystyle x(h-W) = 8Hs $

    And dividing both sides by (h-w) gives the result:

    $\displaystyle x=\frac{8Hs}{h-w} $
