Question 8 of 19 This fest: 100 point(s) possibly This question: 6 pointto) pc Submit test K Solve the following system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent. -x+ y+ 2= -3 - x + 5y -232 = -31 7x - 4y - 252 = 0 Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. A. The solution is ( (Simplify your answers.) B. There are infinitely many solutions. The solution can be written as {(x.y.z)|x=|jy = 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
