stefrheart · Answer

well honestly i think that elimination would be easier

anonymous · Answer

Oh sorry yes! Gosh i typed it wrong.sorry

stefrheart · Answer

oh lol its okay!

anonymous · Answer

Substitution would result in too many odd fractions.

stefrheart · Answer

yes it would :)

stefrheart · Answer

so what is the first step you would do if you do elimination?

anonymous · Answer

Multiply the top equation by 2. But when i tried that and continued to solve, both sides ended up equaling zero. The question is asking me for the answer as an ordered pair

stefrheart · Answer

hmm thats interesting.. did you learn about them being inconsistent, independent, and dependent?

anonymous · Answer

I know x is independent and ybis dependent. Other than that, no.

stefrheart · Answer

no i meant if the equation is independent, dependent, or inconsistent

stefrheart · Answer

what type of algebra are you in?

anonymous · Answer

Im actually in geometry. We are doing an algebra review and i cant seem to remember this problem, along with a couple of others

stefrheart · Answer

ohh okay.. it has to be the same line because if you divide the second one by 2 it creates the same line

anonymous · Answer

But then how would i get the actual variables?

stefrheart · Answer

well you need to find a point on the line
