Consider the reduced offset shape of the matrix augmented by a linear system in 6 variables x, 2, 3, 4, 5, 6 given by (this is the matrix in the image) Suppose that the solution meets the constraints: X1 0, x2 > 0, 3 > 0, 4 > 0, 5 > 0, x6 > 0. If 3=0, then what is the minimum possible value for 6? In this list ?: 49, 21, 28, 63, 42, 0 Question 14 For a non-homogeneous system of equations of 13 equations with 9 unknowns, answer the following questions with (yes / no) 1. Is it possible that the system has a single solution? 2. Is it possible that the system does not have a solution? 3. Is it possible that the system has an infinite number of solutions
