Question

-8s>16 what is the answer

Answer 1

-8s>16
Divide -8 on both sides while flipping the sign from "greater than" to "less than".
Final Answer: s< -2

Answer 2

$-8s\ \textgreater \ 16$
$\frac{-8s}{-8} \ \textgreater \ \frac{16}{-8}$
$s\ \textless \ -2$ 
The sign flips because you are dividing/multiplying both sides with a negative number.
