HELP? WILL MEDAL AND FAN!
I knew it was something like and was told; x-y=x+2 2x-y=4x+2y But I have no idea how to solve this. Could someone show me? or walk me through it?
I think you posted this very same problem earlier, and that I tried to help you with it. What happened, if that's the case?
Didn't we work on this problem together earlier? If so, what happened to your previous post?
"I knew it was something like and was told; x-y=x+2 2x-y=4x+2y Why'd you close that previous post?
x-y=x+2 y=?
Follow sshayer's advice. Find y, if x-y=x+2 (above).
Any ideas?
I can only help you if you try :-)
how did you get that?
Move these terms to the left (-x, -2) It becomes x-y-x-2=0 Eliminate x, -x replacing to (1-1) * x-y-2=0 then 0-y-2=0 , -y-2=0, 0=0 y=-2
Well, I am here.
You have now two equations with two variables. \[x-y=x+2 \\2x-y=4x+2y\] Just arrange them: \[\Large{ y=2 \\3y=-2x}\]
@Rz172 Do you follow?
Ok. Step by step. How can you simplify this one? \[\LARGE x-y=x+2 \]
@Rz172 Do you face any difficulties?
Let me know where you are back!
-2?
what equals to -2????
x-y=x+2 = -2? @3mar
Yes That would be like that! \[\Large x-y=x+2\] \[\Large x-y-x=x+2-x\] \[\Large -y=+2\] \[\Large y=-2\] Did you get the idea?
In 2x−y=4x+2y do we put -2 in y or?
If yes, then it's 3?
Yes, that is right! Plug in (y=-2) and tell what you got!
I got 3
You mean: you got (x=3)??
No, it would be x=-3
Thank you for the medal!
