Thread moved from technical math section, so there is no homework template.
(∀λ∃ℝ)
-x + y - z = 1
-2x + 10y + (2λ + 6) = 6
3x + 11y + (λ2+6)z = 5λ - 1
after gaussian elimination I have this:
-1 4 -2 | 1
0 1 λ | 2
0 0 λ(λ-1) | 5λ
So, for λ=0 ⇒ ∞ solutions, for λ=1 system is impossible and for λ≠0 and λ≠1 only one solution.
Am I right?
