Show clear algebraic working.
(3)
| Scheme | Marks |
|---|---|
| \(18y + 30 = 39\) or \(3y + 5 = 6.5\) | M1 |
| \(18y = 39 - 30\) or \(3y = 6.5 - 5\) | M1 |
| 0.5 oe | A1 |

| (3 marks) |
Notes
M1: M1 for correct expansion {\(18y + 30\)}
A1: Dependent on at least one M1
The mark scheme states that for this question the correct answer alone does not imply a correct method.
