Question

What is the value of n? 40= -5n/8

Answer 1

`40=-(5n)/(8)\ \ \ |Multiply\ by\ 8\ \ \ both\ sides\\\\ 320=-5n\ \ \ |Divide\ by\ (-5)\\\\ n=-64\\\\Solution\ is\ -64.`

Answer 2

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

`40= (-5n)/(8)` /*8

`320=-5n`
Now we can divide both sides by -5

`320=-5n` / :(-5)

`-64=n`

Result is -64
