Answer 2

$\frac{5}{2x} = - 10$



Multiply by 2x on both sides ,



$= > \frac{5}{2x} \times 2x = - 10 \times 2x \\ \\ \\ = > 5 = - 20x$



Divide by - 1 on both side ,



$= > \frac{5}{ - 1} = \frac{20x}{ - 1} \\ \\ \\ = > - 5 = 20x$




Now, divide by 20 on both sides,



$= > \frac{ - 5}{20} = \frac{20x}{20} \\ \\ \\ = > - \frac{1}{4} = x$
