Step-by-step explanation:
[tex] - 3p + \frac{1}{8} = - \frac{1}{4} \\ \\ \therefore \: \frac{1}{8} + \frac{1}{4} = 3p \\ \\ \therefore \: \frac{1}{8} + \frac{1 \times 2}{4 \times 2} = 3p \\ \\ \therefore \: \frac{1}{8} + \frac{2}{8} = 3p \\ \\\therefore \: 3p = \frac{1 + 2}{8} \\ \\ \therefore \: 3p = \frac{3}{8} \\ \\ \therefore \: p = \frac{3}{8 \times 3} \\ \\ \huge \purple{ \boxed{\therefore \: p = \frac{1}{8 }}} \\ \\ [/tex]
