Answer 1

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

• $(\frac{2}{3}s + \frac{5}{6}s) = 21$
• $(\frac{4}{6}s + \frac{5}{6}s) = 21$
• $\frac{9}{6}s = 21$
• $\frac{3}{2}s=21$

Step 2: Multiply both sides by 2/3.

• $\frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}$
• $s = \frac{42}{3}$
• $s = 14$
