A. 2x + y = 8--------> 2x + y = 8 (x + y = 4)(-1)---> -x - y = -4 B. 2x + (4 - x) = 8 C. 2x + y = x + y D. 3x + 2y = 12 E. x = 4
so elimination... time to DRAW! :P
What am I supposed to do?! :( Oh no... :(

Oh wow.. I am just not thinking too much today! Thanks though! :)
C is actually another way to eliminate in this problem
but I think A is what they are getting after
So my answer would be A then correct?
It makes more sense to me if it is.
A is the most likely bet as far as what they are expecting of you
but you get the same results from C so its really a bad question to me
Hm.. alright, thanks! :) I'm just going to go with A.
opps, C is almost lol; C is bad
left off the constants in me head
