v(1)=<6,-7,0> v(2)=<-4,1,-7> v(3)=<8,-24,k> The three vectors form a basis in R3 if and only if k does not equal ____? Thank You, Diggidy

What ideas have you had so far?
Well, i know that v(1) v(2) and v(3) have to be linearly independent they also have to span V.... and i tried putting them into reduced row echelon form but i dont know what to do with the k
What did you get for the rref? As for the k, just treat it like any other number.
