$| x - 1 | - 0.5 = 0$

Step 1

Add $0.5$ to both sides of the equation.

$| x - 1 | = 0.5$

Step 2

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

$x - 1 = \pm 0.5$

Step 3

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

Step 3.1

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

$x - 1 = 0.5$

Step 3.2

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

Step 3.2.1

Add $1$ to both sides of the equation.

$x = 0.5 + 1$

Step 3.2.2

Add $0.5$ and $1$ .

$x = 1.5$

Step 3.3

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

$x - 1 = - 0.5$

Step 3.4

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

Step 3.4.1

Add $1$ to both sides of the equation.

$x = - 0.5 + 1$

Step 3.4.2

Add $- 0.5$ and $1$ .

$x = 0.5$

Step 3.5

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

$x = 1.5, 0.5$
