Can you please help me with this question. I solved the first part, but I'm confused about the span stuff. Can you please provide an explanation for each one Thank you! 

Let x, y, z be (non-zero) vectors and suppose w = 12x + 6y + 4z.
If z = -2x - y, then w =

Using the calculation above, mark the statements below that must be true.
A. Span(x, z) = Span(y, z)
✔B. Span(w, y, z) = Span(x, y)
E. Span(w, x, y) = Span(w, y)
