| Answer | Mark | Mark scheme |
|---|---|---|
| \(7c + 6d\) | M1 | for \(7c\) or \(6d\) |
| A1 | for \(7c + 6d\) |
| Answer | Mark | Mark scheme |
|---|---|---|
| 7 | M1 | for correct method to expand, eg \(5 \times 2m - 5 \times 6\), or divides both sides by 5 as a first step. |
| M1 | for correct method to isolate terms in \(m\), eg \(10m - 30 + 30 = 40 + 30\) | |
| A1 | cao |
| Answer | Mark | Mark scheme |
|---|---|---|
| \(3x + 2y\) | M1 | for \(3x\) or \(2y\) |
| A1 | cao |
