The simplified expression is [tex]\frac{-2a}{33} +\frac{2}{21}[/tex]
Explanation:
The expression is [tex]$\frac{3}{11} a-\frac{4}{7}-\frac{1}{3} a+\frac{2}{3}$[/tex]
Grouping the like terms,
[tex]$\frac{3}{11} a-\frac{1}{3} a-\frac{4}{7}+\frac{2}{3}$[/tex]
Adding the like terms, we get,
[tex]\frac{9a-11a}{33} +\frac{-12+14}{21}[/tex]
Subtracting the values, we have,
[tex]\frac{-2a}{33} +\frac{2}{21}[/tex]
Thus, the simplified expression is [tex]\frac{-2a}{33} +\frac{2}{21}[/tex]
