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

    Multiplying both sides by x -8s we get:

     H(x-8s)=xW
     Hx - 8Hs = xW

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

     Hx - xW -8Hs = 0

    Adding 8Hs to both sides:

     Hx - xW = 8Hs

    Factorising the left hand side:

     x(h-W) = 8Hs

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

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