4MA0 Higher June 2013 Paper 4 Q6
6 Solve \(7y - 6 = 2y + 8\)
Show clear algebraic working.
(3)
| Scheme | Marks |
|---|---|
| \(5y = 14\) or \(7y - 2y = 14\) or \(5y = 8 + 6\) or \(5y - 14 = 0\) | M2 |
| 2.8 | A1 |
| (3) |
Notes
M2: for correct rearrangement with \(y\) terms on one side AND correct collection of terms on at least one side or for correct collection to 2 terms
M1 for correct rearrangement with \(y\) terms on one side and numbers on the other eg \(7y - 2y = 8 + 6\) OR correct collection and simplification of either numbers or \(y\) terms eg \(5y - 6 = 8\) or \(5y = a\) or \(by = 14\)
A1: 2.8 oe dependent on at least one M1
