Ayuda Porfavor a despejar

Answer 1

Hola te ayudare

$10 \times - 5y = 0$

$\times - y = 2$

_________________________

$10 \times - 5y = 0$

$\times = 2 + y$

_________________________

$10(2 + y) - 5y = 0$

_________________________

$y = - 4$

_________________________

$\times = 2 + ( - 4)$

_________________________

$\times = - 2$

_________________________

$( \times .y) = ( - 2. - 4)$

_________________________

$10 \times ( - 2) - 5 \times ( - 4) = 0$

$- 2 - ( - 4) = 2$

_________________________

$0 = 0$

$2 = 2$

_________________________

$\bf{ \pink{( \times .y) = ( - 2. - 4)}}$

Espero que te ayude saludos..
