# What are x and y if 2y+x= - 4 and y-x= - 5?

Oct 27, 2015

$x = 2 , y = - 3$

#### Explanation:

Note that
$y - x = - 5$
$\implies y = x - 5$
Put value of $y$ in $2 y + x = - 4$
$2 \left(x - 5\right) + x = - 4$
$\implies 2 x - 10 + x = - 4$
$\implies 3 x = 6$
$\implies x = 2$
So $y = 2 - 5 = - 3$
