1. The problem statement, all variables and given/known data find the solutions to the following system, depending on the value of the parameter l∈ℝ: lx+y+z=1 x+ly+z=l x+y+lz=l2 Find the value of λ∈ℝ for which the following sytem of linear equations has infinitely many solutions, for such value of λ write down all solutions: x - 2z = 8 x - 3y + λz = 4 2x - λy + z = 12 2. Relevant equations 3. The attempt at a solution I'm not really sure what the questions are asking. Am I supposed to put both of these into an augmented matrix, complete gauss row reduction then rearrange to find the value for l, λ and x,y,z in each question?
