Question
Find $x$, such that: $\frac{-27}{x}=9$
✓
Answer
$\begin{aligned} & \frac{-27}{\mathrm{x}}=9 \\ & \Rightarrow \frac{-27}{\mathrm{x}}=\frac{9}{1} \\ & \Rightarrow \frac{-27}{\mathrm{x}}=\frac{9 \times(-3)}{1 \times(-3)} \\ & \Rightarrow \frac{-27}{\mathrm{x}}=\frac{-27}{-3} \\ & \Rightarrow \mathrm{x}=-3\end{aligned}$
