Question 366514
 I am taking classes with the University of Phoenix and this semester I have algebra. The problems is. -2/7x=6/35. I know that you need to multiply both sides by -7/2, and I know that the answer should be -42/70, but they want me to simplify the answer and I just don't undersand where this magical number is supposed to come from. Help!!!!
---------------
(-2/7) x= 6/35
---
x = (6/35)(-7/2)
----
You have a factor of 2 in the numerator and in the denominator.
You have a factor of 7 in the numerator and in the denominator.
--
2/2 = 1
7/7 = 1
---
So the right side can be written as:
x = (2*3)/(5*7)(-7/2)
x = (2/2)(7/7)(-3/5)
x = 1*1*-3/5
x = -3/5
