$| y | = 5$

Step 1

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

$y = \pm 5$

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.

$y = 5$

Step 2.2

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

$y = - 5$

Step 2.3

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

$y = 5, - 5$
