| Topic | Modulus function |
| Type | Solve |linear| = constant |
| Difficulty | Easy -1.8 This is a straightforward modulus equation requiring only the basic definition: x+3 = ±5, giving x = 2 or x = -8. It's a single-step problem testing recall of the fundamental property of absolute value, significantly easier than average A-level questions which typically require multiple techniques or problem-solving. |
