Question

# The system of linear equations x+y-z=6, x+2y-3z=14 and has a unique solution if

## The correct answer is:

### The system of linear equations x+y-z=6, x+2y-3z=14 and has a unique solution if the determinant of the coefficients is not equal to zero

Hence given equations are

x+y-z=6

x+2y-3z=14

We can draw theirr matrix as

let lamda=x

Hence option B is the correct option
