Answer 4

\[\Huge{\color{green}{\frac{x}{3}+\frac{1}{3}=-\frac{1}{2}}}\]\[\LARGE{\color{red}{\implies\frac{x+1}{3}=-\frac{1}{2}}}\]Now cross multiply :-\[\LARGE{\color{red}{\implies2\times(x+1)=-1\times3}}\]\[\LARGE{\color{red}{\implies2x+2=-3}}\]\[\LARGE{\color{red}{\implies2x=-3-2=-5}}\]\[\LARGE{\color{red}{\implies x=-\frac{5}{2}=-2.5}}\]
