Answer 1

Answer:

Step-by-step explanation:

Answer 2

$\tt{- {\dfrac{1}{3}} \{ 6(p + q) - 3[p - 2(p - 3q)] \}}$

$\tt{\implies - {\dfrac{1}{3}} \{ 6(p + q) - 3[p - 2p + 6q]\}}$

$\tt{\implies - {\dfrac{1}{3}} \{ 6(p + q) - 3p + 6p - 18q\}}$

$\tt{\implies - {\dfrac{1}{3}} \{ 6p + 6q - 3p + 6p - 18q\}}$

$\tt{\implies - {\dfrac{1}{3}} \{ 9p - 12q \}}$

$\tt{\implies - {\dfrac{1}{3}} × 3 \{ 3p - 4q \}}$

$\tt{\implies - {\dfrac{1}{ {\cancel{3}} }} × {\cancel{3}} \{ 3p - 4q \}}$

$\tt\red{\implies 4q - 3p}$
