$| v - 6 | = 5$

Step 1

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

$v - 6 = \pm 5$

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.

$v - 6 = 5$

Step 2.2

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

Step 2.2.1

Add $6$ to both sides of the equation.

$v = 5 + 6$

Step 2.2.2

Add $5$ and $6$ .

$v = 11$

Step 2.3

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

$v - 6 = - 5$

Step 2.4

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

Step 2.4.1

Add $6$ to both sides of the equation.

$v = - 5 + 6$

Step 2.4.2

Add $- 5$ and $6$ .

$v = 1$

Step 2.5

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

$v = 11, 1$
