It keeps giving me an odd answer

Is there a rule against odd numbers?

anonymous · Answer

It wasn't the answer i was looking for

anonymous · Answer

that is because they are the same line

anonymous · Answer

That isn't what it gave me I must have put it in wrong

anonymous · Answer

if you multiply $2x − y = 6$ by 2 you get $4x-2y=12$ so the lines are the same

I believe it is c because the x stands out to be anything, no wonder its called a "variable". So there can be infinite values for x as long as it equals to to the answer.

look here http://www.wolframalpha.com/input/?i=2x+%E2%88%92+y+%3D+6%2C+4x+%E2%88%92+2y+%3D+12 you will see the lines are the same
