1. The problem statement, all variables and given/known data Find all the values of h and k such that the system: hx + 6y = 2 x + (h+1)y = k has: (a) No solutions (b) A unique solution (c) Infinitely many solutions 2. Relevant equations - 3. The attempt at a solution I've tried putting the system into echelon form and got the following (with the augmented matrix): (1 h + 1 k) (0 h2+h-6 hk-2) However, how can i proceed from this step? Note that the only way i can solve this problem is using matrices, i've got the answer by comparing the linear systems but i need to do it with matrices.
