Solve the following system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent. x+y= 5 x-y=-1 CITE Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. The solution is (D). (Simplify your answers.) B. There are infinitely many solutions. The solution can be written as {(x,y)|x=y is any real number} (Simplify your answer. Type an expression using y as the variable as needed.) OC. The system is inconsistent.
