Answer:
x=4 and y=5
Step-by-step explanation:
Find x by adding the two equations so that the 6y and -6y will cancel out.
You're left with 6x=24 which you divide 6 on both sides to get x=4.
Then to find y you will plug 4 into either equation for x. I chose the second equation, so 4-6y=-26, get -6y alone by subtracting the 4 over to the other side. then -6y=-30, then divide both sides by -6 and you get y=5.
X less than or equal to-24
I think the third (and last) answer is correct, because it would successfully eliminate the x variable when adding downwards. If you want me to explain in more detail feel free to ask :)
