${ \color{blue} \begin{gathered}\frac{2}{5}z=\frac{3}{8}z+\frac{7}{20}\\\\\frac{2}{5}z-\frac{3}{8}z=\frac{7}{20}\\\\(\frac{2}{5}-\frac{3}{8}) \times z=\frac{7}{20}\\\\\frac{2 \times 8-3 \times 5}{40} \times z=\frac{7}{20}\\\\z=\frac{7}{20} \times \frac{40}{1}=14\end{gathered}}$

${\mathbb{\colorbox {red} {\boxed{\boxed{\boxed{\boxed{\boxed{\colorbox {pink} {\boxed{\boxed{\boxed{\boxed{\boxed{\colorbox {yellow} {@XxMissCutiepieXx}}}}}}}}}}}}}}}$
