[tex]-( \frac{2x}{xy} ) :[/tex]

Remove parentheses:  (a) = a

[tex]= - \frac{2x}{-xy} [/tex]

Apply  the fraction rule :

[tex] \frac{a}{-b} = - \frac{a}{b} [/tex]

[tex]-( \frac{2x}{xy} )[/tex]

Cancel : [tex] \frac{2x}{xy} [/tex]

[tex]= -(- \frac{2x}{y} )[/tex]

Apply rule : -(-a) = a

[tex]= \frac{2}{y} [/tex]
