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 + 5x₂ + 12x₃ = 6

3x₁ + x₂ + 5x₃ = 12

5x₁ + 8x₂ + 21x₃ = 17
