Answer 2

Answer:

$\frac{-55}{63}$

Step-by-step explanation:

$=\frac{2}{21}(\frac{-3}{13})-\frac{7}{9}-\frac{2}{21}(\frac{10}{13})$

$=\frac{-2}{91}-\frac{7}{9}-\frac{2}{21}(\frac{10}{13})$

$=\frac{-2}{91} +\frac{7}{9} -\frac{2}{21} (\frac{10}{13})$

$=\frac{-655}{819}-\frac{2}{21} (\frac{10}{13} )$

$=\frac{-655}{819}-\frac{20}{273}$

$=\frac{-55}{63}$
