| x | = 7

$| x | = 7$

Step 1

Remove the absolute value term. This creates a

\pm

$\pm$ on the right side of the equation because

| x | = \pm x

$| x | = \pm x$ .

x = \pm 7

$x = \pm 7$

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

$\pm$ to find the first solution.

x = 7

$x = 7$

Step 2.2

Next, use the negative value of the

\pm

$\pm$ to find the second solution.

x = - 7

$x = - 7$

Step 2.3

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

x = 7, - 7

$x = 7, - 7$

x = 7, - 7

$x = 7, - 7$
