If system of equation
x + y + z = 6
x + 2y + 3z = 10
3x + 2y + `lambda`z = `mu` has more than two solutions. Find `(mu -lambda^ )`

The values of lambda and mu such that the system of equations x + y + z = 6, 3x + 5y + 5z = 26, x + 2y + lambda z = mu has no solution, are :

The system of linear equations lambda x + y + z = 3 x - y - 2z = 6 -x + y + z = mu has

Investigate for what values of lambda, mu the simultaneous equations x + y + z = 6, x + 2 y + 3 z = 10 & x + 2 y + lambda z = mu have, An infinite number of solutions.

Investigate for what values of lambda, mu the simultaneous equations x + y + z = 6, x + 2 y + 3 z = 10 & x + 2 y + lambda z = mu have, A unique solution.

The system of equations lambda x + y + 3z = 0, 2x + mu y - z = 0, 5x + 7y + z = 0 has infinitely many solutions in R. Then,

The system of the linear equations x + y – z = 6, x + 2y – 3z = 14 and 2x + 5y – lambdaz = 9 (lambda in R) has a unique solution if
