You can put this solution on YOUR website! (15/x) + (9x-7)/(x+2) =9
------------
Multiply thru by x(x+2) to get:
15(x+2) + (9x-7)x = 9x(x+2)
Expand and then simplify:
15x + 30 + 9x^2 -7x = 9x^2+18x
8x + 30 = 18x
Solve for "x":
10x = 30
x = 3
==================
Checking the answer:
(15/3) + (27-7)/5 = 9
5 + 4 = 9
====================
