Answer:
a = 3 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given
a + 5 [tex]\frac{2}{3}[/tex] = 9 ← change mixed number to improper fraction
a + [tex]\frac{17}{3}[/tex] = 9 ( multiply through by 3 to clear the fraction )
3a + 17 = 27 ( subtract 17 from both sides )
3a = 10 ( divide both sides by 3 )
a = [tex]\frac{10}{3}[/tex] = 3 [tex]\frac{1}{3}[/tex]
