# How do you solve 8y = -16 and -10x + 8y = 64 ?

Jul 29, 2016

$x = - 8$
$y = - 2$

#### Explanation:

By putting $8 y = - 16$ in the equation $- 10 x + 8 y = 64$
we get
$- 10 x - 16 = 64$
or
$- 10 x = 64 + 16$
or
$- 10 x = 80$
or
$x = - \frac{80}{10}$
or
$x = - 8$========Ans $1$

$8 y = - 16$
or
$y = - \frac{16}{8}$
or
$y = - 2$========Ans $2$
