Every human society has a culture. Why do you think that culture is so important to groups? What elements of culture make it a necessary part of any human group or society?

Find which value of k does the system of equations

x - 3y + z = -2

- x + 5y - z = 0

4x - 14y + kz = -5

have infinitely many solutions? For that particular value of k, solve the system of equations for x, y and z.

A solution with parameters may be entered as e.g.:[t,-9/2-6*t,3/2+3*t].

[k,x,y,z] = 

Please Help :) and explain in detail, thank you!
