{tex}\left(\frac{2}{3}+\frac{3}{5}\right)+x=\frac{-2}{15} {/tex}
{tex} \Rightarrow\left(\frac{10+9}{15}\right)+x=\frac{-2}{15}{/tex}
{tex}\Rightarrow \frac{19}{15}+x=\frac{-2}{15}{/tex}
{tex}\Rightarrow x=\frac{-2}{15}-\frac{19}{15}{/tex}
{tex}\Rightarrow x=\frac{-2-19}{15}{/tex}
{tex}\Rightarrow x= \frac{-21}{15}{/tex}
Therefore, the unknown no.is {tex}\frac{-21}{15}{/tex}
