Los op vir x en kies die regte antwoord as \( \left( {3 - x} \right)\left( {5 - x} \right) = 3 \)

\( \begin{align} \left( {3 - x} \right)\left( {5 - x} \right) &= 3\\ 15 - 8x + {x^2} &= 3\\ {x^2} - 8x + 12 &= 0\\ \left( {x - 6} \right)\left( {x - 2} \right) &= 0\\ x = 6\,\,of\,\,x = 2 \end{align} \)
