x+2y=3 x+y=1

OpenStudy (thebatman):

Are you looking for x or y?

OpenStudy (anonymous):

Y

OpenStudy (thebatman):

Ok. You know to re-arrange and substitute right?

OpenStudy (anonymous):

I think the easier way to solve for this is by using the elimination method.

OpenStudy (anonymous):

You can cancel out the x and solve for y manually.

OpenStudy (anonymous):

Well can you do it

OpenStudy (anonymous):

Ill start it off. x+2y=3 (-1) x+y=1 Mult. the bottom by -1 ____________________________________ x+2y=3 -x-y = -1 + x and -x cancels each other out. Subtract y --------------------- y= ? I think you know? :)

OpenStudy (anonymous):

-1 on both sides

OpenStudy (anonymous):

yes sorry I didnt elaborate that.

OpenStudy (anonymous):

Yeah lol its good

OpenStudy (anonymous):
