"How has the Internet affected culture?"

Present at least two detailed paragraphs answering this question. Think about the definition of culture and perhaps present specific examples of how the Internet has affected culture.

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!
