I found:
$x=-13$
$y=-7$

Isolate $x$ from the first equation and substitute it into the second to find $y$ as:

$x=y-6$

into the second:

$-2(y-6)+3y=5$

$-2y+12+3y=5$
$y=-7$

use this value back into the first equation:
$x=-7-6=-13$

How do you solve the following system?: x - y = -6, -2x+3y=5 x - y = -6, -2x+3y=5
