\( x = 9\frac{7}{11} - 3\frac{3}{11} \)
\( x = (9-3) + (\frac{7}{11}-\frac{3}{11}) \)
\( x = 6 + \frac{4}{11} \)
\( x = 6\frac{4}{11} \)
\( x = 10\frac{2}{13} - 2\frac{4}{13} \)
\( x = 9\frac{15}{13} - 2\frac{4}{13} \)
\( x = (9-2) + (\frac{15}{13}-\frac{4}{13}) \)
\( x = 7 + \frac{11}{13} \)
\( x = 7\frac{11}{13} \)
