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.

4x₁- 2x₂ - 3x₃ + x₄ = 3

2x₁ - 2x₂ - 5x₃ = -10

4x₁ + x₂ + 2x₃ + x₄ = 17

3x₁ + x₃ + x₄ = 12
