\large\bold{\underline{\underline{Given:-}}}

3(n - 5) =  - 21

\large\bold{\underline{\underline{To\:find:-}}}

The value of n.

\large\bold{\underline{\underline{Solution:-}}}

:⟼  3(n - 5) =  - 21

:⟼  3n - 15 =  - 21

:⟼  3n =  - 21 + 15

:⟼  3n =  - 6

:⟼  n =  \frac{ - 6}{3}  \\

:⟼  \boxed{   n=-2 }

\large\bold{\underline{\underline{To\:verify:-}}}

:⟼  3( - 2 - 5) =  - 21

:⟼  3( - 7) =  - 21

:⟼   - 21 =  - 21

:⟼  L. H. S. = R. H. S.

Hence verified.
