1. The problem statement, all variables and given/known data express the vector (6,-4,7) as a linear combination of (4,-2,1) and (-3,1,2) 2. Relevant equations 3. The attempt at a solution I am not quite sure how to go at it but this is what I am assuming to do: (C1*4,C2*-2,C3*1)=(6,-4,7) C1=3/2 C2=2 C3=7 and the same method for the 2nd one? I know how to show linear dependence and dependence as a vector is independent if c1=c2=c3 and not if constants aren't equal. Any help in how to solve this is appreciated.
