Had trouble reading your post. It's important that you separate each equation with plenty of spaces, or, b etter yet, type only one equation per line:
<span>x-y=19 -2x+y/6=28 should be:
</span><span> x-y=19
-2x+y/6=28
Does (-31,-56) satisfy this system? Is (-31) - (-52) = 19? No. Move on to the next system and check again whether or not (-31, -56) is a solution.</span>
