Suppose that 
and 
are three non-coplanar vectors in R 3 . Let the components of a vector 
along 
and 
be 4, 3 and 5, respectively. If the components of this vector 
along 
and 
are x, y and z, respectively, then the value of 2x + y + z is
Text Solution
Verified by Experts9
(9) 
– x + y – z = 4
x – y – z = 3
x + y + z = 5
On solving we get x = 4, 
2x + y + z = 9
