Question

How do you graph and solve `abs (5+x) <=20`?

Answer 1

`x in [-25, 15]` In bold face,show the segment of the x-axis, representing the closed interval [-25, 15]. Here, `|5+x|<=20`

Explanation:

`|5+x|<=20` is the combined inequality for the pair

`+-(5+x)<=20`.

Separately, these are

`x<=15 and x>=-25`.
