\fQuestion number 11. Given that the augmented matrix in row-reduced form below is equivalent to the augmented matrix of a system of linear equations. Determine whether the system has a solution and find the solution(s) to the system, if they exist. (Note: The dotted vertical line in the matrix above should be a single vertical line.) No solution. [ x= -7 + z, y=4, z = any real number ] [ x= -7 - z, y= 4, z = any real number ] [ x=-7, y=-4,2=-7] [x=-7, y=4] O None of the above
