Step-by-step explanation:

1)

 \frac{ \frac{3}{7}z -  \frac{1}{2}  }{z -  \frac{1}{4} }  -  \frac{3}{14}  =  \frac{1}{7}  \\  \frac{ \frac{6z - 7}{14} }{ \frac{4z - 1}{4} }   =  \frac{1}{7}  +  \frac{3}{14}  \\  \frac{6z - 7}{14}  \times  \frac{4}{4z - 1}  =  \frac{2 + 3}{14}  \\  \frac{4(6z - 7)}{14(4z - 1)}  =  \frac{5}{14}  \\  \frac{24z - 28}{4z - 1}  = 5 \\ 24z - 28 = 5(4z - 1) \\ 24z - 28 = 20z - 5 \\ 24z - 20z = 28 - 5 \\ 4z = 23 \\ z =  \frac{23}{4}

2)

 \frac{p -  \frac{2}{5} }{p +  \frac{2}{5} }  = 5 \\  \frac{ \frac{5p - 2}{5} }{ \frac{5p + 2}{5} }  = 5 \\  \frac{5p - 2}{5p + 2}  = 5 \\ 5p - 2 = 5(5p + 2) \\ 5p - 2 = 25p + 2 \\ 5p - 25p = 2 + 2 \\  - 20p = 4 \\ p =  -  \frac{4}{20}  \\ p =  -  \frac{1}{5}
