[tex]40=-\frac{5n}{8}\ \ \ |Multiply\ by\ 8\ \ \ both\ sides\\\\ 320=-5n\ \ \ |Divide\ by\ (-5)\\\\ n=-64\\\\Solution\ is\ -64.[/tex]
To find value of n, we have to have only one n of the RHS.
To do this, we can multiply both sides by 8
[tex]40= \frac{-5n}{8} [/tex] /*8
[tex]320=-5n[/tex]
Now we can divide both sides by -5
[tex]320=-5n[/tex]  / :(-5)
[tex]-64=n[/tex]

Result is -64
