\[T = 5P - W\](a) Work out the value of \(T\) when \(\quad P = 4 \quad\) and \(\quad W = 2\) [2 marks]
(b) Work out the value of \(P\) when \(\quad T = -40 \quad\) and \(\quad W = 10\) [3 marks]

|---|---|---|
| \(-40 + 10\) or \(-30\) or \(-40 = 5P - 10\) or \(P = \dfrac{T + W}{5}\) | M1 | |
| their \(-30 \div 5\) | M1dep | |
| \(-6\) | A1 | SC2 \(-10\) with \(-50\) seen |
Additional guidance
| Embedded answer of \(-6\) | M1M1A0 |
| SC2 \(-10\) with \(-50\) seen for \(-40 + 10 = -50\) and then \(\div 5\) | |
| \(-40 = 5P - 10\) may use a different letter or symbol for \(P\) but not \(T\) or \(W\) |
