Solve the system of equations. If the system has no solution, say that it is inconsistent. 3x - 3y + 42 = 4 9x - 8y + 9z = 10 -3x + 4y - 72 = -7 Select the correct choice below and fill in any answer boxes within your choice. O A. The solution of the system is x = y = and z = (Simplify your answers.) O B. There are infinitely many solutions. Using ordered triplets, the solution can be written as {(x,y,z) |x = ,y = , z any real number}. (Simplify your answers. Type expressions using z as the variable as needed.) O C. There are infinitely many solutions. Using ordered triplets, the solution can be written as (x,y,z) |x = , y any real number, z any real number} (Simplify your answer. Type an expression using y and z as the variables as needed.) O D. The system is inconsistent
