You can put this solution on YOUR website!
6/y+2+1/y-2=1
----
6/(y+2) + 1/(y-2) = 1
---
Multiply thru by (y+2)(y-2) to get:
6(y-2) + 1(y+2) = (y+2)(y-2)
-------
6y-12 + y+2 = y^2-4
-----
y^2 -7y +6 = 0
---
Factor:
(y-6)(y-1) = 0
-----
y = 1 is an extraneous solution:
----
y = 6 is a valid solution.
