7
(a) Simplify \(\;10x + 4y + 3x - 6y\) (2)
(b) Solve \(\;2n + 5 = 16\) (2)
| Scheme | Marks |
|---|---|
| \(13x - 2y\) | B2 |
| (2) |
Notes
B2: accept \(-2y + 13x\)
(B1 for \(13x\) or \(-2y\))
| Scheme | Marks |
|---|---|
| \(2n = 16 - 5\) or \(2n = 11\) oe or \((16 - 5) \div 2\) | M1 |
| 5.5 | A1 |
| (2) | |
| (4 marks) |
Notes
M1: for a correct first step
or a correct calculation for \(n\)
A1: for 5.5 or \(\dfrac{11}{2}\) or \(5\dfrac{1}{2}\)
