Solve each absolute value equation
2=|x|-1

x = ±3

Step-by-step explanation:

2 = |x| - 1

Add 1 to both sides:  |x| = 3

⇒ x = ±3

Solution:

Remember, the number inside the absolute value bars will always be positive. This means that if -5 is between two bars, it will become 5.

Let's review 2 ways that this equation can go through:

Hence, the measure of x is ±3.
