June 2023 Paper 2 Q1
1 Solve \(\quad \dfrac{8d - 3}{3d - 7} = \dfrac{5}{2}\) [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(2(8d - 3)\) or \(5(3d - 7)\) or \(\dfrac{5}{2}(3d - 7)\) or \(\dfrac{2}{5}(8d - 3)\) | M1 | oe eg \(16d - 6\) or \(15d - 35\) may be seen in an equation |
| \(16d - 6 = 15d - 35\) or \(8d - 3 = \dfrac{15}{2}d - \dfrac{35}{2}\) or \(\dfrac{16}{5}d - \dfrac{6}{5} = 3d - 7\) | M1dep | oe equation with brackets expanded |
| \(-29\) | A1 |
Additional guidance
| Up to M2 may be awarded for correct work with no answer or incorrect answer, even if this is seen amongst multiple attempts | |
| Missing brackets must be recovered | |
| Embedded answer | M2A0 |
| \(2\left(\dfrac{8d - 3}{3d - 7}\right) = 5\) with no further correct work | M0 |
