$x=-2 \ & \ y=0$

Given system of linear equations:

$2x-5y=-4\ ..........(1)$

$-2x+3y=4\ ............(2)$

Now, adding (1) & (2) as follows

$2x-5y-2x+3y=-4+4$

$-2y=0$

$y=0$

setting $y=0$ in (1) we get

$2x-5(0)=-4$

$2x=-4$

$x=-2$

How do you solve the following linear system: 2x-5y=-4, -2x+3y=4, 2x−5y=−4,−2x+3y=4, 2x-5y=-4, -2x+3y=4, ?
