$3 + 2 = 2 + | 2 y |$

Step 1

Rewrite the equation as $2 + | 2 y | = 3 + 2$ .

$2 + | 2 y | = 3 + 2$

Step 2

Add $3$ and $2$ .

$2 + | 2 y | = 5$

Step 3

Move all terms not containing $| 2 y |$ to the right side of the equation.

Step 3.1

Subtract $2$ from both sides of the equation.

$| 2 y | = 5 - 2$

Step 3.2

Subtract $2$ from $5$ .

$| 2 y | = 3$

Step 4

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

$2 y = \pm 3$

Step 5

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