Homework Statement
express the vector (6,-4,7) as a linear combination of (4,-2,1) and (-3,1,2)
Homework Equations
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.
