Question

Please help me to do this problem please. if 1/2+2/5s=s-3/4,what is the value of S?

Answer 1

Answer: We are provided with one unknown equation and we have to solve it:

`(1)/(2)+(2)/(5)s=s-(3)/(5)`

The solution for s is :

`\begin{gathered} (2)/(5)s-s=-(3)/(5)-(1)/(2)=(-6-5)/(10)=-(11)/(10) \\ (2s-5s)/(5)=-(11)/(10) \end{gathered}`

Therefore the solution is as follows:

`-3s=-(11)/(2)\rightarrow s=(11)/(6)`
