Solve the system of equations. If the system has no solution, say that it is inconsistent. X- y- z = 1 -x + 2y - 3z = -4 4x-2y-12z = -2 Select the correct choice below and, if necessary, fill in any answer boxes within your choice. y= OA. The solution is x = and z = (Type integers or simplified fractions.) OB. There are infinitely many solutions. The solution set is {(x,y,z) | x= (Simplify your answers. Type expressions using z as the variable.) y= z is any real number}. y is any real number, z is any real number} O C. There are infinitely many solutions. The solution set is {(x,y,z) | x= (Simplify your answer. Type an expression using y and z as the variables.) OD. The system is inconsistent.
