You can put this solution on YOUR website! One divded by the sum of a number and 4 plus one divided by the difference of a number and 4 is the same as the reciprocal of the difference of a number squared and 16. Find the number.
-----
1/(x+4) + 1/(x-4) = 1/(x^2-16)
--------
Multiply thru by x^2-16 to get:
(x-4) + (x+4) = 1
2x = 1
x = 1/2
