Explain why we may assume x10. (Hint: x1 is the first unknown because u₁ was the first vector in our spanning set.) ,un} is a set of vectors that span V, and that {V1, V2, ..., Vk} is an independent set of Suppose {u1, u2, ..., 1 vectors in V. Explain why V1 x1u1 + x2u2+ ...+xnun -must have a solution.
