Solve the following system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent. x- y = 1 3x-4z = 6 3y+2z = 3 Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. OA. The solution is ()- (Simplify your answers.) OB. There are infinitely many solutions. The solution can be written as {(x,y,z)|xyz is any real number} (Simplify your answers. Type expressions using z as the variable.) OC. There are infinitely many solutions. The solution can be written as {(x,y,z)|xy is any real number, z is any real number}. (Simplify your answer. Type an expression using y and z as the variables.) OD. The system is inconsistent.
