Use Gaussian elimination to find the complete solution to the following system of​ equations, or show that none exists.

{-x + y + z = -1

{-x + 5y -15z = -29

{ 7x - 6y - 11z = 0

Find the​ row-echelon form of the matrix for the given system of equations.

​(Do not include the vertical bar in the augmented​ matrix.)

Select the correct choice below​ and, if​ necessary, fill in the answer boxes to complete your choice.

A. There is one solution. The solution set is {(_, _, _)}

​(Simplify your​ answers.)

B. There are infinitely many solutions. The solution set is {(_, _, z)}where z is any real number.

​(Type expressions using z as the variable. Use integers or fractions for any numbers in the​ expressions.)

C. There is no solution. The solution set is empty set∅.

Solve the following system of linear equations: 3x2−9x3 = −3 x1−2x2+x3 = 2 x2−3x3 = 0 If the system has no solution, demonstrate this by giving a row-echelon form of the augmented matrix for the system. If the system has infinitely many solutions, your answer may use expressions involving the parameters r, s, and t. You can resize a matrix (when appropriate) by clicking and dragging the bottom-right corner of the matrix.
