# Modulus Inequality! watch

1. solve for x:
|5x+a|<=|2x| where a>0
That's a less than equal to sign, can't find the button here for it, sorry!

I did:
5x+a<= 2x
x<= -a/3

-5-a>= 2x
x<= -a/7

But can it be done algebraically, with out graphs?
The answer worked out when I sketched the graphs.

It can but this is way too advanced and messy, so it is not worth it
