five divided by the sum of a number and 4, minus the quotient of 3 and the difference of the number and 4 is equal to 6 times the reciprocal of the difference of the number squared and 16. What is the number?
-----------
5/(x+4) - 3/(x-4) = 6/(x^2-16)
------
Multiply thru by x^2-16 to get:
-----
5(x-4) - 3(x+4) = 6
----
2x -32 = 6
2x = 38
---
x = 19
