1.	The system of equations:`x+y+z=5``x+2y+3z=9``x+3y+lambdaz=mu`has a unique solution, if`lambda=5,mu=13`(b) `lambda!=5``lambda=5,mu!=13`(d) `mu!=13`
Answer» `2 lamda + 3 + 3 - 2 - 9 - lamda != 0` `lamda != 5` `/_\_3 = \|(1,1,5),(1,2,9),(1,3,mu)\| != 0` `2 mu + 15 + 9 - 10 - 27 - mu != 0` `mu != 13` option b is correct
