Hey. We're learning a new chapter in algebra now and I don't really understand it at all =(. I want to get ahead and figure it out before we have a test or quiz so help would be Greatly appreciated! I'm in ninth grade and doing Algebra. We're working on solving linear systems by graphing. If anyone can explain two of these problems step by step (literally) I would be SO happy and wish that I'd be able to give you a medal =)Ok here it goes. number 30. -3x+y=10 and the second one that goes to this is 7x+y=20 My question is what do you do step-by step and how do u graph it? Sorry I know this is REALLY confusing but I know someone out there can help me! Thank you sooo much in advance! =) (link)

-3x+y=10 7x+y=20
+3x +3x
----------
y= 10+3x plug this equation in to the other one
y= 10+3 7x+10+3x=20
y= 13 10x+10=20
-10 -10
------------
10x=10
-------
10 10
----------
x=1 plug x in to the other equation
Sorry it is so hard to follow, it's really hard to show without arrows and oral explanation. If you have any questions just ask.
I hope I Helped
