Find x such that:
$\frac{-1}{5}=\frac{8}{\text{x}}$
$\frac{-1}{5}=\frac{8}{\text{x}}$
✓
Answer
$\frac{-1}{5}=\frac{8}{\text{x}}$$\Rightarrow-1\times\text{x}=8\times5$
$\Rightarrow-\text{x}=40$
$\Rightarrow\text{x}=-40$
$\therefore\text{x}=-40$
$\Rightarrow-\text{x}=40$
$\Rightarrow\text{x}=-40$
$\therefore\text{x}=-40$
