$| x | = 4$

Step 1

Remove the absolute value term. This creates a $\pm$ on the right side of the equation because $| x | = \pm x$ .

$x = \pm 4$

Step 2

The complete solution is the result of both the positive and negative portions of the solution.

Step 2.1

First, use the positive value of the $\pm$ to find the first solution.

$x = 4$

Step 2.2

Next, use the negative value of the $\pm$ to find the second solution.

$x = - 4$

Step 2.3

The complete solution is the result of both the positive and negative portions of the solution.

$x = 4, - 4$
