Let x,y,z be (non-zero) vectors and suppose w=2y−2x+z.

If z=x−y, then w= x. + y.

Using the calculation above, mark the statements below that must be true.

A. Span(w, x, y) = Span(w, y)
B. Span(w, x, z) = Span(x, z)
C. Span(w, z) = Span(x, y)
D. Span(w, x, y) = Span(w, z)
E. Span(w, y, z) = Span(y, z)
