\frac{5}{7}  -  \frac{7}{3}  -  \frac{3}{7}  +  \frac{11}{3} = \frac{5}{7}-  \frac{3}{7}    +  \frac{11}{3}-  \frac{7}{3}\\

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: =  \frac{2}{7}  +  \frac{4}{3}  \\

  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: =  \:  \frac{6 + 28}{21}  \\

  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: =  \frac{34}{21}  \\
