Homework Statement
Bonus] Let E = {“ax+by+cz = d” | a; b; c; d ∈ R} be the set of linear equations
with real coefficients in the variables x, y and z. Equip E with the usual operations
on equations that you learned in high school: addition of equations, denoted here
by “⊕” and multiplication by scalars, denoted here by “~”, as follows:
“ax + by + cz = d” ⊕ “ex + fy + gz = h” = “(a + e)x + (b + f)y + (c + g)z = d + h”
and
∀k ∈ R; k ~ “ax + by + cz = d” = “ka x + kb y + kc z = k d”:
You may assume without proof that E is a vector space.
Find a spanning set for E.
(You must justify your answer.)

I have no idea what this question is asking...isnit the span just span{x,y,z}? o.o
