Solve the following system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent. -x+ y+ z=-2 - x + 5y - 23z = - 26 6x - 4y - 18z = 0 Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The solution is (Simplify your answers.) O B. There are infinitely many solutions. The solution can be written as (x,y,z) |x = , y= , z is any real number} . (Simplify your answers. Type expressions using z as the variable.) O C. There are infinitely many solutions. The solution can be written as (x,y,z) |x = , y is any real number, z is any real number}. (Simplify your answer. Type an expression using y and z as the variables.) O D. The system is inconsistent.Tell whether the given rational expression is proper or improper.
