Answer:
-7 and 7
Step-by-step explanation:
|x|=7|x|=7
Remove the absolute value term. This creates a ±± on the right side of the equation because |x|=±x|x|=±x.
x=±7x=±7
Set up the positive portion of the ±± solution.
x=7x=7
Set up the negative portion of the ±± solution.
x=−7x=-7
The solution to the equation includes both the positive and negative portions of the solution.
x=7,−7x=7,-7
