$| v | = 12 j$

Step 1

Solve the equation for $v$ .

Step 1.1

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

$v = \pm 12 j$

Step 1.2

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

Step 1.2.1

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

$v = 12 j$

Step 1.2.2

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

$v = - 12 j$

Step 1.2.3

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

$v = 12 j$

$v = - 12 j$

$v = 12 j$

$v = - 12 j$

$v = 12 j$

$v = - 12 j$

Step 2

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be $0$ or $1$ for each of its variables. In this case, the degree of the variable in the equation violates the linear equation definition, which means that the equation is not a linear equation.
