| Topic | Modulus function |
| Type | Solve |linear| = constant |
| Difficulty | Easy -1.8 This is a straightforward absolute value equation requiring only the basic definition: solve 2x - 3 = 9 and 2x - 3 = -9 to get x = 6 and x = -3. It's a routine algebraic manipulation with no problem-solving required, significantly easier than average A-level questions. |
