zehanz · Answer

I would add the two equations.
Do you know what method this is?

anonymous · Answer

Actually no i don't. I have no idea.. :(

zehanz · Answer

Well, if I add them, 7x and -7x add up to 0, so gone is the variable x!
Seems like elimination to me...

anonymous · Answer

Thanks so much! :)

zehanz · Answer

YW!

(remember,  from now on, you know what is meant by elimination!)
