25 Make \(w\) the subject of the formula \(y = 3w - 10\) (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(w = \dfrac{y + 10}{3}\) | M1 | for \(y + 10 = 3w\) or \(\dfrac{y}{3} = w - \dfrac{10}{3}\) |
| A1 | for \(w = \dfrac{y + 10}{3}\) oe |
Additional guidance
Accept \(w = \dfrac{-y - 10}{-3}\) for M1A1
