Solution
We need to solve the equation involving the absolute value:
Step 1: Isolate the absolute value term
First, isolate the absolute value by adding 8 to both sides of the equation:
Step 2: Set up two cases
The absolute value equation can be written as two separate equations:
Step 3: Solve both cases
Case 1:
Add 4 to both sides: Divide by 2:
Case 2:
Add 4 to both sides: Divide by 2:
Step 4: Final answer
