Question

find all numbers whose absolute value is 3. if there is more than one, separate them with commas. if there are no such numbers, click on
one\.

Explanation:

Step1: Recall absolute value definition

The absolute value of a number \( x \), denoted \( |x| \), is the distance of \( x \) from 0 on the number line. So \( |x| = 3 \) means \( x \) is 3 units from 0.

Step2: Solve for \( x \)

Numbers 3 units from 0 are \( 3 \) (to the right of 0) and \( -3 \) (to the left of 0), since \( |3| = 3 \) and \( |-3| = 3 \).

Answer:

-3, 3
