Step 2.2.1

Multiply $7$ by $5$ .

$| x | = 35$

Step 3

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

$x = \pm 35$

Step 4

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

Step 4.1

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

$x = 35$

Step 4.2

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

$x = - 35$

Step 4.3

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

$x = 35, - 35$
