Question

There are 2 points of questions here about linear eq..

Answer 1

part a: Find a system of linear eq in the variables x1, x2, x3, whose solution set is given by the parametric eq x1=t; x2= 1+t; x3=2-t

and I got the answer, please check...
x1-x2 = -1
x3 + x1=2

part b: find another parametric solution to the system in part a in which the parameter is s and x3 =s
I hv my answer but not sure can anyone help for part b?? thank youu

Answer 2

@candyfloss94 you have three variables x1, x2 and x3
so you need to create three equation. You have made 2, find one more

Answer 3

oh sorry, for part a it said,"find a system of TWO linear eq in the variables x1, x2, x3..." so I think my answer's enough, is it?

Answer 4

oh then it's correct:)

Answer 5

part b is also similar
so
x1=s
x2=1+s
ans x3=s

Answer 6

so that's the parametric solutions you give??

Answer 7

@ash2326 how about...
because x3=s=2-t then

x3=s
x2=3-s
x1=2-s

which one is correct then? :/

Answer 8

Sorry that was just the question for part b
we have
x1=s
x2=1+s
and x3=s

Answer 9

Yeah you're right. I'm sorry, I got confused

Answer 10

ah I see... that's alright. thanks so much for quick reply. I thought you've gone :o :p :)

Answer 11

I was here:)
Sorry and thanks:)
