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
