In Problems 1122, use elementary row operations to transform each augmented coefficient matrix to echelon form. Then
Question:
In Problems 11–22, use elementary row operations to transform each augmented coefficient matrix to echelon form. Then solve the system by back substitution.
2x1 + 4x2 - x3 - 2x4 + 2x5 = 6
x1 + 3x2 + 2x3 - 7x4 + 3x5 = 9
5x1 + 8x2 - 7x3 + 6x4 + x5 = 4
