Question

solve the system by elimination method
-2x+y+6=0
2x+y-8=0
when you eliminate x, what is the resulting equation? MEDALS

Answer 1

please try and explain how you got the answer so i know how to do the rest correctly

Answer 2

There is no solution

Answer 3

there has to be this is multiple choice @denonakavro

Answer 4

Yes there is

Answer 5

You have 2x-2x already so just got your constants to the other side and than add everything

Answer 6

a.2y=2
b. 2y=-2
c. y=-2

Answer 7

Move your constants to the other side

Answer 8

The 6 and -8

Answer 9

okay give me a sec imma try to work it out and tell me if im right

Answer 10

Okay :)

Answer 11

? You getting it? :)

Answer 12

this is what i did and i have no idea if this is correct
-2x+y+6=0 + 2x+y-8=0
+-8 +8
-2x+y-2=0 + 2x+y=0
+-2x +-2x
y-2=0+y=0
y y
2y =-2

Answer 14

Your very close

Answer 15

dang it

Answer 16

When you did the -2x+y+6=0 you subtract -6 from both sides so you have -2x+y=-6
The other one 2x+y-8=0 put the 8 to the other side so add it 2x+y=8
-2x+y=-6
2x+y=8
Now add these

Answer 17

do you understand where I got these

Answer 18

On the one you did you were close you got 2y but when you moved the two to the other side you didn't add it -2+2=0 so you have to add the 2 to the other side 2y=2

Answer 19

yes since you subtracting you got the -6 and so on

Answer 20

okay so i understand the subtracting but what happens when i add it for future reference because i have 15 other questions like this @kayders1997

Answer 21

So like where my also step was? Where I had the two equations?

Answer 22

yes

Answer 23

-2x+y=-6 (so add -2x+2x=0x y+y=2y -6+8=2 (don't need to put in 0x like I did))
2x+y=8
---------
0x+2y=2
So 2y=2

Answer 24

Sorry that wasn't supposed to go down that far

Answer 25

okay now i see thank you :)

Answer 26

No problem :)

Answer 27

thanks for your patience im terrible at math

Answer 28

That's okay, I understand everyone is at different levels at math, and that it can be hard for some, and like I tell people I don't care how long it takes to explain something, as long As you would understand what is going on :)
