$| x - 5 | = 3$

Step 1

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

$x - 5 = \pm 3$

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.

$x - 5 = 3$

Step 2.2

Move all terms not containing $x$ to the right side of the equation.

Step 2.2.1

Add $5$ to both sides of the equation.

$x = 3 + 5$

Step 2.2.2

Add $3$ and $5$ .

$x = 8$

Step 2.3

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

$x - 5 = - 3$

Step 2.4

Move all terms not containing $x$ to the right side of the equation.

Step 2.4.1

Add $5$ to both sides of the equation.

$x = - 3 + 5$

Step 2.4.2

Add $- 3$ and $5$ .

$x = 2$

Step 2.5

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

$x = 8, 2$
