Answer:

$\boxed {s = 14}$

Step-by-step explanation:

Solve for the value of $s$ :

$\frac{2}{3}s + \frac{5}{6}s = 21$

-Combine like terms:

$\frac{2}{3}s + \frac{5}{6}s = 21$

$\frac{3}{2}s = 21$

-Multiply $\frac{2}{3}$ on both sides, which is the reciprocal of $\frac{3}{2}$ , and multiply $21$ and $2$ :

$s = 21 \times (\frac{2}{3})$

$s = \frac{21 \times 2}{3}$

$s = \frac{42}{3}$

-Divide $42$ by $3$ :

$s = \frac{42}{3}$

$\boxed {s = 14}$

Therefore, the value of $s$ is $14$ .
