Answer:

$No\ Solutions$

Step-by-step explanation:

$We\ are\ given\ that,\\-x+2y=7\\x-2y=7\\By\ simply\ adding\ the\ system\ of\ equations,\\(-x+x)+(2y-2y)=(7+7)\\0+0=14\\Hence,\\0=14\\As\ the\ equation\ above\ doesnt\ make\ sense\ as\ 0\ doesn't\ equal\ to\ 14,\\There\ are\ no\ solutions\ that\ satisfy\ the\ equation.$
