Solve for y |y|=3

$| y | = 3$

Step 1

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

$y = \pm 3$

Step 2

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

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

$y = 3$

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

$y = - 3$

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

$y = 3, - 3$
