If the system of linear equations given by \(x+y+z=3,2 x+2 y-z=3, x+y-z=1\) is consistent and if \(\left(x_0, y_0, z_0\right)\) is a solution, then \(2 x_0+2 y_0+z_0=\)
- A 0
- B 5
- C 7
- D 6
Answer & Solution
Correct Answer
(B) 5
Step-by-step Solution
Detailed explanation
In consistent adding Eqs. (i) and (iii), we get \[ 2 x+2 y=4 \Rightarrow x+y=2 \] put in Eq. (i) \[ 2+z=3 \Rightarrow z=1 \] Then,…
