Elimination method |
2009-10-08 |
|
From Kenty:
How do I solve this problem using the elimination method?
3x-7y=0
6x+4y=0
I am not sure how so if someone can show me a similar problem (instead of
solving this one for me) that would be fantastic.

From Rose:
I have been having trouble trying to figure out these three math problems , I need help breaking them down so I could understand them better please help.
1. x = 7 - x
2 x - y + 8
2. 8 x + 5 y = 1 8 4
x - y = 3
3. y + 2 x = 3
y + 2 x = 4
I can't figure out how to break them down in the right order.
