Hi,

I am wondering if anyone could help me with this system or linear equations with parameterk. I've tried using reduced row echelon form, but I'm not sure about my answer. This is the problem:

x_{1 }- x_{3 }= -3

3x_{1}+ 6x_{2}+ 3kx_{3}= 3

kx_{2}+ 5x_{3}= 4

2x_{1}+ kx_{2}- x_{3}= -2

Thank you for your help!
