√b/a-x= √a



Square both sides:



When you square both sides you take away the
radical:



Multiply both sides by (a-x)



Cancel on the left.  Distribute on the right



      b = a² - a·x

Add a·x to both sides:

b + a·x = a²

Subtract b from both sides:

    a·x = a² - b

Divide both sides by a:

   

Cancel the a's on the left

   

   x =
