Transcribed Image Text:Solve the following system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent.
x+3y-z = 7
2x-6y +z = 1
- 2x + 3y - 4z = 7
Select the correct choice below and, if necessary, fill in the answer box(es) in your choice.
O A. The solution is (110).
(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.)
