Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

  • [tex](\frac{2}{3}s + \frac{5}{6}s) = 21[/tex]
  • [tex](\frac{4}{6}s + \frac{5}{6}s) = 21[/tex]
  • [tex]\frac{9}{6}s = 21[/tex]
  • [tex]\frac{3}{2}s=21[/tex]

Step 2: Multiply both sides by 2/3.

  • [tex]\frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}[/tex]
  • [tex]s = \frac{42}{3}[/tex]
  • [tex]s = 14[/tex]
