Question
Solve:
$\frac{3\text{x}}{5\text{x}+2}=-4$
✓

Answer

$\frac{3\text{x}}{5\text{x}+2}=-4$
$\Rightarrow\frac{3\text{x}​​}{5\text{x}+2}=\frac{-4}{1}$
$\Rightarrow1(3\text{x})=-4(5\text{x}+2)$ (by cross multiplication)
$\Rightarrow3\text{x}=-20\text{x}-8$
$\Rightarrow3\text{x}+20\text{x}=-8$
$\Rightarrow23\text{x}=-8$
$\Rightarrow\text{x}=\frac{-8}{23}$
$\therefore\text{x}=\frac{-8}{23}$
