Consider the following system of equations: 3)) y + w + x + 2y = 4 u + y + w + x - y - I = 2 2n - 3w + s + a = 3 -u + 2w + x + y - z = 1 u _ 1.? - 2-2 = i} A} Transfonn the augmented matrix {A | 1}} into its Echelon Form by performing a sequence of elementary row operations. Without solving for the general solution, determine if a can be chosen arbitrarily. Repeat for x and y.
