Higher November 2023 Paper 2 Q4
4 Solve \(5x - 14 = 52 - x\) (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 11 | M1 | for one correct step to isolate \(x\) term or constant term on one side, eg adds \(x\) to both sides to get \(5x - 14 + x = 52 - x + x\) or adds 14 to both sides to get \(5x - 14 + 14 = 52 - x + 14\) oe |
| M1 | for both correct steps to isolate terms in \(x\) on one side and constant term on one side, eg \(\text{``}6x\text{''} - 14 + 14 = 52 + 14\), or \(5x + x = \text{``}66\text{''} + x - x\) | |

Additional guidance
May be seen in different equivalent forms but must be carried out, not just intention seen.
Can be implied by eg \(4x = 66\) or \(6x = 38\)
