\(x + 2y + 3z = − 1\)

\(3x + 2y + z = 9\)

Add both equations

4x+4y+4z=8

x+y+z = 2

In this question, we have been given 3 equations:

Equation 1 is \(2x+y+2z=4\),
Equation 2 is \(x+2y+3z=−1\),
Equation 3 is \(3x+2y+z=9.\)

On adding Equation 2 and Equation 3 we get:

\(x+2y+3z=-1\)
\(3x+2y+z= 9\)
---------------
\(4x+4y+4z=8\).

On dividing the entire equation by 4 we get the \(x+y+z=2\) .

Therefore, the OA is B
