Find the point of intersection of the pair using the method of elimination x-y = 3 2x + y = 3
If you just add the two equations, the y will be eliminated. Can you do that?
I don't understand what the question is exactly asking
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
Ok Katrina and karate will help you.
Can anybody solve it for me? I don't really get what you're trying to say....
Ok. One min. My explanations will be followed.
add the equations together (x+2x)+(-y+y)=(3+3) that should help
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?
therefore lleaving the equation to be x=3 2x=3
Since they cancel each other, the equation becomes: 3x = 6
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)
now you take that 2 and plug it into one of the equations
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
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
Now since you have solved x and y, your coordinates of intersection is (2, - 1)
woops i messed up make that be -1
nice work kat!;) medal timne!!!
That will be your final answer. Any questions?
Thank you so much. God bless <3
KC and KK helping people with math? Has the world turned upside down?
Anytime Waleed =)
@hero what wrong with that? i have always helped people with the math tht i know..
It's when both of you do it together....that's what makes it strange.
???
its called TEAMWORK!
i'm a one man team.
ok kool;)
the more the merrier :D
:D
will only be happier
