Divide 3x into 18xyt = 6yt
---
? = 6yt
===============================
Find the LCD for the given rational expressions, and convert
each rational expression into an equivalent rational expression
with the LCD as the denominator
4/(x - y), 5x/(2y - 2x)
---
Factor:
4/(x-y) ; 5x[-2(x-y)]
-------------------
LCD = -2(x-y)
----
(4*-2)/LCD ; 5x/LCD
===========================
