Foundation June 2023 Paper 1 Q22
22 Expand and simplify fully \(\quad 5(3x + 4) - 2(x - 1)\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(13x + 22\) | B2 | B1 \(15x + 20\) or \(-2x + 2\) or \(13x + a\) or \(bx + 22\), where \(a\) and \(b\) can be any numbers |
Additional guidance
| Do not ignore further working for B2 eg \(13x + 22 = 35x\) eg \(13x + 22,\ x = \dfrac{22}{13}\) | B1 B1 |
