Answer: The possible values are less than 4 but greater than –4.

Explanation:

Given: Javier writes an integer on a piece of paper. The absolute value of his number is less than 4.

Let the integer written by Javier be x.

Thus, according to the given situation.,

`|x|>4`

⇒ x>4 and -x>4

⇒x>4 and x<-4 [by multiplying (-1) on both sides , the inequality reverse]

⇒-4<x<4

⇒The possible values are less than 4 but greater than –4.
