The unique solution is w = X= y= and z = (Simplify your answers.) OB. The system has infinitely many solutions. The solutions are of the form w = (Simplify your answers. Type expressions using r as the variable. Do not factor.) OC. The system has infinitely many solutions. The solutions are of the form w = X= (Simplify your answers. Type expressions using r and s as the variables. Do not factor.) OD. The system has infinitely many solutions. The solutions are of the form w = and z = r, where r is any real number. , y=r, and z=s, where r and s are any real numbers. x=r, y=s, and z = t, where r, s, and t are any real numbers. (Simplify your answer. Type an expression using r, s, and t as the variables. Do not factor.) E. There is no solution.
