Answer
$$ s = 8 $$
Explanation
$$ \begin{aligned} 6\cdot(13-s)+4s &= 62&& \text{simplify left side} \\[1 em]78-6s+4s &= 62&& \\[1 em]-2s+78 &= 62&& \text{ move 78 to the right } \\[1 em]-2s &= 62-78&& \\[1 em]-2s &= -16&& \text{ divide both sides by $ -2 $ } \\[1 em]s &= \frac{-16}{-2}&& \\[1 em]s &= 8&& \\[1 em] \end{aligned} $$
