Answer 2

★ Solution (1) :-

$\sf \leadsto \dfrac{n}{5} - \dfrac{1}{4} = \dfrac{-2n}{5} - \dfrac{1}{12}$

$\sf \leadsto \dfrac{n}{5} + \dfrac{2n}{5} = - \dfrac{1}{12} + \dfrac{1}{4}$

$\sf \dashrightarrow \dfrac{3n}{5} = \dfrac{-1 + 3}{12}$

$\sf \dashrightarrow \dfrac{3n}{5} = \dfrac{2}{12}$

$\sf \dashrightarrow \dfrac{3n}{5} = \dfrac{1}{6}$

$\sf \dashrightarrow 6(3n) = 5$

$\sf \dashrightarrow 18n = 5$

$\sf \dashrightarrow n = \dfrac{5}{18}$

★ Solution (2) :-

$\sf \dashrightarrow \dfrac{2n}{4} - \dfrac{3}{2} = \dfrac{8n}{2} - \dfrac{1}{4}$

$\sf \dashrightarrow \dfrac{2n}{4} - \dfrac{8n}{2} = - \dfrac{1}{4} + \dfrac{3}{2}$

$\sf \dashrightarrow \dfrac{2n - 16n}{4} = \dfrac{-1 + 6}{4}$

$\sf \dashrightarrow \dfrac{-14n}{4} = \dfrac{5}{4}$

$\sf \dashrightarrow -14n = 5$

$\sf \dashrightarrow n = \dfrac{5}{-14}$

$\sf \dashrightarrow n = \dfrac{-5}{14}$

★ Solution (3) :-

$\sf \dashrightarrow n - 3 = 5 - 2n$

$\sf \dashrightarrow n + 2n = 5 + 3$

$\sf \dashrightarrow 3n = 8$

$\sf \dashrightarrow n = \dfrac{8}{3}$

$\sf \dashrightarrow n = 2 \dfrac{2}{3}$

★ Solution (4) :-

$\sf \dashrightarrow 2n - \dfrac{1}{3} - \dfrac{5}{3} = n$

$\sf \dashrightarrow 2n - \dfrac{-4}{3} = n$

$\sf \dashrightarrow \dfrac{6n + 4}{3} = n$

$\sf \dashrightarrow 6n + 4 = 3n$

$\sf \dashrightarrow 6n - 3n = -4$

$\sf \dashrightarrow 3n = -4$

$\sf \dashrightarrow n = \dfrac{-4}{3}$

$\sf \dashrightarrow n = -1 \dfrac{1}{3}$

Hence, solved!!
