\[\textbf{а)}\ x + \frac{3}{17} = \frac{14}{17}\]

\[x = \frac{14}{17} - \frac{3}{17}\]

\[x = \frac{11}{17}.\]

\[\textbf{б)}\ \frac{4}{11} + y = \frac{5}{11}\]

\[y = \frac{5}{11} - \frac{4}{11}\]

\[y = \frac{1}{11}.\]

\[\textbf{в)}\ a - \frac{3}{8} = \frac{2}{8}\]

\[a = \frac{2}{8} + \frac{3}{8}\ \]

\[a = \frac{5}{8}.\]

\[\textbf{г)}\ \frac{5}{13} - b = \frac{2}{13}\]

\[b = \frac{5}{13} - \frac{2}{13}\]

\[b = \frac{3}{13}.\]

\[\textbf{д)}\ c + \frac{8}{15} = \frac{12}{15}\]

\[c = \frac{12}{15} - \frac{8}{15}\]

\[c = \frac{4}{15}.\]

\[\textbf{е)}\ \frac{11}{43} - x = \frac{3}{43}\]

\[x = \frac{11}{43} - \frac{3}{43}\]

\[x = \frac{8}{43}.\]

\[\boxed{\mathbf{6.}}\]
