Systems of Equations
x + y = 0
5x + 2y = 3
this is what i got so far....
x + y = 0 > x = 0  y
5x + 2y(0y) = 3
please help!!!!

you have it right so far

i know but can you please help me do the rest

you take 2 times 0 to get rid of the y, then you have 5x= negative three figure out x or else you are never going to learn. Is this due tomorrow?

yes
you don't have to give me the answer
I just wanted you to write it out so that I can understand and figure out the answer myself. 
2x0=0
5x=3
what is x? 
x + y = 0
5x + 2y = 3
y=x
5x+2(x)=3
5x2x=3
3x=3
divide both sides by 3 
i got 0.6.... i don't think that's the answer for x...
I'm solving for x and then I have to su solve for y 
that is not right what grade are you in bobpursley?

gtg

bobpursley is a teacher on jiskha hw help

5x + 2y(0y) = 3
don't you minus 2y on both sides (under y)???? 
yeah.you are right.
