In Exercises 43-46, determine the values of a for which the system has no solutions, exactly one solution, or infinitely many solutions. x+ y+ 7z=-7 2x+3y+ 17z =-16 x + 2y + (a2+ 1)z = 3a EXPERT ANSWER
EXPERT ANSWER Subtract second and the 3rd equations which gives 3x + 9y + ( – 13)z= a + 13 ……. (1) multiply 3 to equation x + 3y -3z =5 i.e 3x +9y -9z =15 …………………………………(2) now this equation 2 which is a equation of a plane will be parellel to equation 1 or equal to equation 1 depending on the …
