Foundation June 2025 Paper 2 Q10

10 Lui is asked to work out the value of \(30 - 4x\) when \(x = -5\)

Here is his working and his answer.

\[\begin{aligned} 30 - 4x &= 30 - 4 \times -5 \\ &= 30 - 20 \\ &= 10 \end{aligned}\]

Lui’s answer is wrong.

Oni thinks of a number.
She calls the number \(Y\)

\(Y\) is a positive, odd number and \(Y \leqslant 9\)
