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!!!!

**Jessica**, Thursday, January 31, 2013 at 8:50pmyou 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?

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.

**bobpursley**, Thursday, January 31, 2013 at 9:00pmx + y = 0

5x + 2y = -3

y=-x

5x+2(-x)=-3

5x-2x=-3

3x=-3

divide both sides by 3
