Solve the following system of linear equations: 5x2+10x3 = -60 5x2+5x3 = -35 x1-3x2-x3 = 9 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, select "The system has at least one solution". Your answer may use expressions involving the parameters 1, s, and t. You can resize a matrix (when appropriate) by clicking and dragging the bottom-right corner of the matrix. The system has no solutions The system has no solutions The system has at least one solution Row-ecreion form of augmented matrix: 000 000 000

Use pivots and row operations to solve the following system. Show all of your row operations and your intervening matrices. Write the final matrix in triangular for and solve by using back substitution. A. 2x+y - z=1 x + 2y + z = 8 x + y - 2z = -3

Solve the following system of linear equations: 3x1-3x2-3x3 -3 -3x1+6x2 = 0 -x1-2x2+4x3 = 5 If the system has no solution, demonstrate this by giving a row-echelon form of the augmented matrix for the system. You can resize a matrix (when appropriate) by clicking and dragging the bottom-right corner of the matrix. The system has a unique solution The system has no solution The system has a unique solution The system has infinitely many solutions x3
