Question 833655: 4/x + 4/x-15 =1
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! 4/x + 4/(x-15) = 1
-------
Multiply thru by x(x-15) to get:
4(x-15) + 4x = x(x-15)
---------
x^2 - 15x = 8x - 60
------
x^2 - 23x + 60 = 0
-----------
(x-3)(x-20) = 0
--------------
x = 3 or x = 20
-----------------
Check those "answers" to see if either or both are extraneous.
