______________________

$1. \: p(8 - 2) = 12$

$\therefore p(6) = 12$

$\therefore p = 12 \div 6$

$\green \Longrightarrow \blue{\fbox{p = 2}}$

$2. \: ( - 5)(z + 2) = - 4$

$\therefore - 5z - 10 = - 4$

$\therefore - 5z = - 4 + 10$

$\therefore - 5z = 6$

$\green \Longrightarrow \blue{ \boxed{ z = - \frac{6}{5} }}$

$3. \: 6(k - 3) = 8$

$\therefore 6k - 18 = 8$

$\therefore 6k = 8 - 18$

$\therefore 6k = - 10$

$\therefore k = - \frac{10}{6}$

$\green \Longrightarrow \blue{ \boxed{ k = - \frac{5}{3} }}$

Answer 2

Answer:

$p(8 - 2) = 12 \\ p(6) = 12 \\ p = \frac{12}{6} \\ p = 2 \\ 2. \: \: ( - 5)(z + 2) = - 4 \\ \\ - 5z + ( - 10) = - 4 \\ 5z - 10 = - 4 \\ 5z = - 4 - 10 \\ 5z = 14 \\ z = -\frac{14}{5} \\ \\ \\ 3. \: \: \: \: 6(k - 3) = 8 \\ \\ 6k - 18 = 8 \\ \\ 6k = 8 - 18 \\ \\ 6k = - 10 \\ k = \frac{-10}{6} \\ \\ k = - \frac{5}{3}$
