Question

Please help!!! I don't understand this.

Answer 1

what dont u understand

Answer 2

What is the solution of the system of equations?

Answer 3

what is the question?

Answer 4

What is the solution of the system of equations?
3x + 2y + z = 7
5x + 5y +4z = 3
3x + 2y + 3z = 1

Answer 5

and each variable has to be consistent in each equation

Answer 6

i believe so

Answer 7

ok that gives me a challenge of a sort.........
but not much of a challenge

Answer 8

ive never done problems like this before

Answer 9

its ok i will help

Answer 10

thank you so much :) Whats the 1st step

Answer 11

what ur teacher is sick man i dont even know this

Answer 12

the first step is to look at the equations and see what you can find out about each one for instance from looking at all of the equations i can say that for each equation X is going to be different from the others, and the same thing for Y and Z

Answer 13

so there for you will have 3 answers for each variable

Answer 14

okay :)

Answer 15

in the first equation i can say that if Z =1 that you will have to say that X is going to be a 2 and the y is going to be a 0 but there are many different ways to make them all add up to 7 such as
X=1 Y=3 and Z=1
that is what i would say for the first one

Answer 16

are you following what i am saying

Answer 17

starting to make sence :) btw thanks a million for taking time to help me

Answer 18

no problem

Answer 19

for the second one
if Z = -1 than X= 0 or 1 and Y= 0 or 1 but if X=0 than Y= 1 and vise versa

Answer 20

that makes more sense the way your explaining it than my teacher did

Answer 21

thank you very much
and for the final one
if Z=1 than X=0 and Y=-1
or if Z=0 than x=1 and Y=-1

Answer 22

so there you have it as a set of equations if you need to find out a set of answers that work for all of them that the answer would have to be no solution

Answer 23

You are very welcome and thank youuuu soooooooo much for all of your kind help

Answer 24

no problem snow
