(i) x y + 2z = 1 (ii) x(y + 2z) = 3 (iii) Find the augmented matrix for the following system of linear equations: x1 = 2x2 1. Let " 1 1 0 0 0 0. 0 0 1 1 0 0 ( be the augmented matrix for a system of linear equations. Find the solution to the system of linear equations whose augmented matrix is. Find the value(s) of k for which the system has in nitely many solutions. C: all k = 1 d: k = 0 only. Use the following information for questions 7 and 8. Consider the system of linear equations with augmented matrix. Find the value(s) of k for which the system has no solution. Find the value(s) of k for which the system has exactly one solution.
