| Topic | Simultaneous equations |
| Type | Simultaneous with substitution elimination |
| Difficulty | Standard +0.3 This is a standard C1 simultaneous equations question combining one linear and one quadratic equation. While it requires substitution and solving a resulting quadratic, the algebraic manipulation is straightforward with no unusual complications. The 7 marks reflect routine working rather than conceptual difficulty, making it slightly easier than the average A-level question which typically involves more problem-solving or integration of multiple techniques. |
