For what values of `aa n db ,` the system of equations `2x+a y+6z=8` `x+2y+b z=5` `x+y+3z=4` has: (i) a unique solution (ii) infinitely many solutions no solution

Text Solution

AI Generated Solution

To solve the problem, we need to analyze the system of equations given: 1. \(2x + ay + 6z = 8\) (Equation 1) 2. \(x + 2y + bz = 5\) (Equation 2) 3. \(x + y + 3z = 4\) (Equation 3) We will use determinants to find the conditions for unique solutions, infinitely many solutions, and no solutions. ...
