Foundation June 2022 Unit 1 Q17
17. Solve the following equation. [3]
\[8x - 38 = 17 - 3x\]| Scheme | Marks | Comments |
|---|---|---|
| \(8x + 3x = 17 + 38\) OR \(-17 - 38 = -8x - 3x\) | B1 | FT until 2nd error. |
| \(11x = 55\) OR \(-55 = -11x\) | B1 | |
| \(x = 5\) | B1 | Mark final answer. If FT leads to a whole number answer, it must be shown as a whole number. Otherwise, accept a fraction. Allow B1B1B1 for a correct embedded answer BUT only B1B1B0 if contradicted by \(x \neq 5\) |
