# How do you solve the system 6x-y=-145 and x=4-2y?

Jun 1, 2018

$x = - 22 , y = 13$

#### Explanation:

Plugging $x = 4 - 2 y$ in the first equation we get
$6 \left(4 - 2 y\right) - y = - 145$
expanding
$24 - 12 y - y = - 145$
so
$- 13 y = - 169$

so

$y = 13$

we get $x$ as

$x = 4 - 26$

$x = - 22$
