Question

4x – y + z = 6
3x + 2y – z = 0
4x – y – 3z = 2

Answer 1

4x-y+z=6
-/4x-y-3z=2

4z=4 ----> z=1

2/4x-y=5
3x+2y=1

11x=11 -----> x =1 so y=-2

Answer 2

But my choices are..
7x + y = 6

x – y = 6

x + y = 6

7x – y = 6

Answer 3

my mistake

Answer 4

y=3

Answer 5

you got an elimination problem.....or substitution....can both of you handle it ?

Answer 6

oh my god I am making mistakes all the time

Answer 7

y=3 is not one of my choices..sorry

Answer 8

y=-1 okey

Answer 9

you got 3 equations.....not 2...remember that

Answer 10

so it is the first one 7x + y = 6 correct!!!!

Answer 11

Do you need me to do the problem ?

Answer 12

Please

Answer 13

That dude dont no what the heck he is doing and id appreciate an example

Answer 14

Hold on...this will take a little while...I will soon post the answer :)

Im definitely complaining about this site later on. This is ridiculous they have moderators that wont say anything but people who use the site do.

Answer 29

Oh good!! im still a little confused. i understand how you got that far. but how does it relate to my answer choices?

Answer 30

Appreciate that..x=1, y=-1, z=1 so the answer 7x+y=6 :)

Answer 38

4x-y+z=6
-/4x-y-3z=2

4z=4 ----> z=1

2/4x-y=5
3x+2y=1

11x=11 -----> x =1 -----> y=-1 then

your choices are
7x + y = 6

x – y = 6

x + y = 6

7x – y = 6

If you put the values I found in these equations, you can see the answer as 7x+y=6

Answer 39

@saifoo.khan good site..you know any site for engineering electromagnetics

Answer 41

Hey listen up....those answer choices cannot be the answer to this problem...if you finished this problem you would get the answer to all the integers for instance....x = ? or y = ?......the answer choices that are given are not in that form. However, when you add just the first 2 equations...this is what you get...
4x - y + z = 6
3x + 2y - z = 0
-------------add
7x + y = 6

This is not the answer to the entire problem, but it is a step in the problem....is this what you want ? If so, then this is your answer :)
