Solving Absolute Value Equations:
Case 1:
$$a|bx + c| + d=k$$
- Isolate the absolute value operation on the left side:
- There should be a single non-negative number on the right side
- Note: if the right side is a negative number, you have no solution
- Note: if the right side is 0, just drop the absolute value bars and solve the resulting equation
- Set up a compound equation with "or"
- Set the expression inside of the absolute value bars equal to the number on the right side
- Set the expression inside of the absolute value bars equal to the negative of the number on the right side
- Solve the resulting equations
