Solve simultaneous equations using substitution method.
\( \begin{array}{l}\text{Solve: } x + 3 \times y = 13, 2 \times x + y = 11\end{array} \)
Choose one option:
Substitute carefully and simplify each step to avoid mistakes.
Substitute \(y = 11 - 2 \times x\) into \(x + 3 \times y = 13\), solve for x, then y.
