Question

Consider the system:
x + 2z =1
x+2y+4z =1
2x-y+3z=2
For all solutions {x,y,z}, find the range of k such that \(k(x^2-3) > yz \)

Answer 1

I don't know!! :'(

Answer 2

hmm i can find values of x , y and z but don;t know what to do after wards with them

Answer 3

Same here...

Answer 4

lol sorry guess not much help i am

Answer 5

Wait, can you find the numerical values for x, y, z?

Answer 6

sure , give me a moment.

Answer 7

what about first finding the solution set of the system using algebra matrix

Answer 8

Gaussian elimination method.
