Question

Use Cramer's rule to solve the system of equations. If D=0, use another method to determine the solution set 7x-y + 8z -49 3x + 7y -z = 37 X+ 8y + 72 = 78 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O A. There is one solution. The solution set is {(k-} (Type integers or simplified fractions.) O B. There are infinitely many solutions. The solution set is {2)), where z is any real number (Simplify your answers. Use integers or fractions for any numbers in the expressions) OC. There is no solution. The solution set is
