algebra
I need to know if I am doing this problem right when sustitution method. y+2x=3 y+2x=-4 y+2x=3 -1(y+2x=3)-y-2x=-4 now add the two equation y-2x=3 -y-2x-4 the answer would be -4y=7 then divided -4=7 answer 1.75 I no that there is more to this answer I am just stuck and not sure...

Ok so let me start over. System of equation can be solved by graphing, substitution or elmination method. I only have to choose one method and I was trying the elimination method is that how my problem seems to be?

Alegbra
System of equation. substitution or elmination method??

Alegbra
yes

I would like to know if I did these problem right? y + 2x =3 Y +2x=-4 Y+2*x-3=0 y=2*x+4=0 If not can you show me the steps

Can someone help me with this one and how to find the equation? Suppose you are paying your cell phone bill. The function C(m) represents the cost C of your monthly cell phone bill with m minutes. Given the equation: What does the number 0.25 represent?
