ok, whenever you have the absolute value sign, you have two representations of the content in the sign

In this case:

x + 2, and the opposite, -x – 2

So you have (and keep in mind I don’t have the less than or equal to/greater than or equal to signs):

x + 2 – x > 0

2 > 0

and

-x – 2 – x > 0

-2x – 2 > 0

-2x > 2

x < - 1 So there's only one solution for x

you have one positive x and one negative x so they cancel each other out so your left with 21>0
