If you just add the two equations, the y will be eliminated. Can you do that?

- anonymous

I don't understand what the question is exactly asking

- KatrinaKaif

You have to solve for x and y, concluding with an ordered pair of (x,y)

well elimination is where you eliminate one of the variables to be able to solve the equation

- Mertsj

Ok Katrina and karate will help you.

- anonymous

Can anybody solve it for me? I don't really get what you're trying to say....

- KatrinaKaif

Ok. One min. My explanations will be followed.

- myininaya

add the equations together
(x+2x)+(-y+y)=(3+3)
that should help

- KatrinaKaif

Your equations are:
x - y = 3
2x + y = 3
In both equations "-y" from the first equation, and "+y" from the second equation cancel each other out. Understood?

- karatechopper

therefore lleaving the equation to be x=3
2x=3

- KatrinaKaif

Since they cancel each other,
the equation becomes:
3x = 6

- KatrinaKaif

Now lets solve for x.
Divide both sides for 3, which concludes us with the answer
x = 2
Since we have solved for x, our ordered pair would be (2,y)

- karatechopper

now you take that 2 and plug it into one of the equations

- karatechopper

im going to take the x-y=3 equation
so i plug 2 in for x
2-y=3
subtract 2 on both sides
-y=1
divide by -1 on both sides
y=1

- KatrinaKaif

Now, use what you have found as being x= 2, and plug it into your original equation.
Lets plug "2" in the position of "x" in equation one:
x - y = 3
(2) - y = 3
Bring the 2 to the "other side" but substracting it from 3
-y = 3 - 2
-y = 1
Divide by -1
and your answer is
y = -1

- KatrinaKaif

Now since you have solved x and y, your coordinates of intersection is (2, - 1)

- karatechopper

woops i messed up make that be -1

- karatechopper

nice work kat!;) medal timne!!!

- KatrinaKaif

That will be your final answer. Any questions?

- anonymous

Thank you so much. God bless <3

KC and KK helping people with math? Has the world turned upside down?

- KatrinaKaif

Anytime Waleed =)

- karatechopper

@hero what wrong with that? i have always helped people with the math tht i know..

- Hero

It's when both of you do it together....that's what makes it strange.

- karatechopper

???

- karatechopper

its called TEAMWORK!

- Hero

i'm a one man team.

- karatechopper

ok kool;)
