[tex]{ \qquad\qquad\huge\underline{{\sf Answer}}} [/tex]
Here's the solution ~
[tex]\qquad \sf \dashrightarrow \: n - 3n = 14 - 4n[/tex]
[tex]\qquad \sf \dashrightarrow \: - 2n + 4n =14 [/tex]
[tex]\qquad \sf \dashrightarrow \: 2n = 14[/tex]
[tex]\qquad \sf \dashrightarrow \: n = 14 \div 2[/tex]
[tex]\qquad \sf \dashrightarrow \: n = 7[/tex]
Value of n is 7
