Solution
To find a statement that is equivalent to the given absolute value equation , we can rewrite the absolute value equation without the absolute value by setting up two separate equations based on the definition of absolute value:
Definition of Absolute Value:
Applying this Definition:
Given the equation , we can rewrite it as:
Solving Each Equation:
-
For : Add 8 to both sides: Divide by 2:
-
For : Add 8 to both sides: Divide by 2:
