3.2 Problems The linear systems in Problems 1-10 are in echelon form. Solve each by back substitution. 1. x1 + x2 + 2x3 = 5 x2 + 3x3 = 6 x3 = 2 3. x₁ - 3x2 + 4x3 = 7 x2 - 5x3 = 2 5. x1 + x2 - 2x3 + x4 = 9 X2 X3 + 2x4 = 1 x3 - 3x4 = 5 2. 2x1 - 5x2 + x3 = 2 3x22x3 = 9 x3 = -3 4. x1 - 5x2 + 2x3 = 10 X2 - 7x3 = 5 6. x12x2 + 5x3 - 3x4 = x2-3x3 + 2x4 = 3 7 X4 = -4
