SOLUTION: I times by the x and by 2y and did the same on the others side with the 5x and 4y to try to get lcm.My answer was way off from the book.

2/x - 3/2y + 3/5x -1/4y Thank-you Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 2/x - 3/2y + 3/5x -1/4y
-----------------
lcd = 20xy
-------------------
Rewrite each fraction with the lcd as its denominator:
---
(40y/lcd) - (30x/lcd) + (12y/lcd) - (5x/lcd)
------------------
Combine the numerators over the lcd:
---
[40y - 30x + 12y -5x)/lcd
---
Simplify:
(52y - 35x)/(20xy)
==============================
