Multi-Step Equations

Systems of Equations

x + y = 0
5x + 2y = -3

this is what i got so far....

x + y = 0 ----> x = 0 - y

5x + 2y(0-y) = -3

please help!!!!

you have it right so far

i know but can you please help me do the rest

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
5x-2x=-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(0-y) = -3

don't you minus 2y on both sides (under -y)????
