$s = 4$ $s = 4$

Explanation:

$3 r = 10 + 5 s$ $3r = 10 + 5s$
$" "$
Substitute the value of $r = 10$ $r= 10$
$" "$
$\Rightarrow 3 \times 10 = 10 + 5 s$ $rArr 3 xx 10 = 10 + 5s$
$" "$
$\Rightarrow 30 = 10 + 5 s$ $rArr 30 = 10 + 5s$
$" "$
$\Rightarrow 30 - 10 = 5 s$ $rArr 30 -10 = 5s$
$" "$
$\Rightarrow 20 = 5 s$ $rArr 20= 5s$
$" "$
$\Rightarrow \frac{20}{5} = s$ $rArr 20/5 = s$
$" "$
$therefore s = 4" "$ when $" " r= 10$
