17
(a) Solve \(3x - 5 \lt 16\) (2)
(b) Solve \(\dfrac{11 - w}{4} = 1 + w\) (3)
| Answer | Mark | Notes |
|---|---|---|
| \(x \lt 7\) | 2 | M1 for isolating term in \(x\) eg \(3x \lt 16 + 5\) or \(3x \lt 21\) or for \((x =)\ 7\) or \(x \gt 7\) etc A1 cao |
| Answer | Mark | Notes |
|---|---|---|
| \(\dfrac{7}{5}\) | 3 | M1 for multiplying by 4 or adding \(\dfrac{w}{4}\) or subtracting \(\dfrac{11}{4}\) or subtracting 1 [all applied to both sides and as a first step] M1 for isolating terms in \(w\) on one side and number terms on the other side of the equation A1 for \(\dfrac{7}{5}\) oe |
