$\frac{ \frac{3}{7} z - \frac{1}{2} }{z - \frac{1}{4} } - \frac{3}{14} = \frac{1}{7} \\ \\ = > \frac{ \frac{(3z)(2) - (1)(7)}{14} }{ \frac{4z - 1}{4} } = \frac{1}{7} + \frac{3}{14} \\ \\ = > \frac{ \frac{6z - 7}{14} }{ \frac{4z - 1}{4} } = \frac{2 + 3}{14} \\ \\ = > \frac{6z - 7}{14} \times \frac{4}{4z - 1} = \frac{5}{14} \\ \\ = > \frac{4(6z - 7)}{14(4z - 1)} = \frac{5}{14} \\ \\ = > \frac{24z - 28}{56z - 14} = \frac{5}{14} \\ \\ Cross \: Multiplication \\ \\ = > 14(24z - 28) = 5(56z - 14) \\ \\ = > 336z - 392 = 280z - 70 \\ \\ = > 336z - 280z = - 70 + 392 \\ \\ = > 56z = 322 \\ \\ = > z = \frac{322}{56} = \frac{161}{28}$
