\bf{Move \ the \ negative \ symbol \ to \ the \ left. }


\boldsymbol{\sf{-(10n)/(5)=-4 \ \ \longmapsto \ \ [Split] }}


\boldsymbol{\sf{-2n=-4 }}


\bf{Divide \ both \ sides \ by \ -2. }


\boldsymbol{\sf{n=(-4)/(-2) }}


\bf{Two \ negatives \ make \ a \ positive. }


\boldsymbol{\sf{n=(4)/(2) \ \ \longmapsto \ \ [Split] }}


\blue{\boxed{\boldsymbol{\sf{Answer \ \ \longmapsto \ \underline{n=2}}}}}
