Homework Statement
if v_1,v_2,...,v_k be k linear independent vector, and if
v_1,v_2,...v_k,v be k+1 linear dependent vector, then
v is the linear combination of v_1,v_2,...,v_k
Homework Equations

The Attempt at a Solution
some of my attempt,(direct proof)
v_1,v_2,...v_k,v be k+1 linear dependent vector then when we write v_1,v_2,...v_k,v as linear combination of 0, there exist some coefficient not all of them 0. and i still no idea how to relate it to "v_1,v_2,...,v_k be k linear independent vector"
