Please see the graph.
Work Step by Step
$2x-4y=22$
$5x-10y=15$
$2x-4y=22$
$2x-4y+4y=22+4y$
$2x=22+4y$
$2x/2=(22+4y)/2$
$x=11+2y$
$5x-10y=15$
$5(11+2y)-10y=15$
$55+10y-10y=15$
$55=15$ (false statement)
$2x-4y=22$
$(2x-4y)*-2.5=22*-2.5$
$-5x+10y=-55$
$5x-10y=15$
$5x-10y+(-5x+10y)=15+(-55)$
$5x-10y-5x+10y=-40$
$0=-40$ (false statement)
