Answer :
Answer: We are provided with one unknown equation and we have to solve it:
[tex]\frac{1}{2}+\frac{2}{5}s=s-\frac{3}{5}[/tex]The solution for s is :
[tex]\begin{gathered} \frac{2}{5}s-s=-\frac{3}{5}-\frac{1}{2}=\frac{-6-5}{10}=-\frac{11}{10} \\ \frac{2s-5s}{5}=-\frac{11}{10} \end{gathered}[/tex]Therefore the solution is as follows:
[tex]-3s=-\frac{11}{2}\rightarrow s=\frac{11}{6}[/tex]
