Solution
Let's analyze the equation , where:
We are tasked with solving the equation:
Step 1: Solve for
The absolute value equation can be rewritten as two separate cases:
Case 1: Multiply both sides by 4 to eliminate the denominator: Now, solve for :
Case 2: Multiply both sides by 4: Now, solve for :
Step 2: Verify the Solutions
For :
Both sides are equal, so is a solution.
For :
Both sides are equal, so is also a solution.
Conclusion
The solutions to the equation are and .
