Students frequently perform the following type of calculation to introduce a zero into a matrix. 3R₂-2R₁ 3 1 0 10 1 24 However, 3R₂ - 2R₁ is not an elementary row operation. Why not? O 3R₂ - 2R₁ is not an elementary row operation since the coefficient of R₂ is -2. O 3R₂ - 2R₁ is not an elementary row operation since it does not include the interchanging of two rows. O 3R₂ - 2R₁ is not an elementary row operation since the coefficient of R₂ is 3. 3R₂ - 2R₁ is not an elementary row operation since the coefficient of R₁ is 2. O 3R₂ - 2R₁ is not an elementary row operation since the coefficient of R₁ is -3. Show how to achieve the same result using elementary row operations. - First perform the elementary row operation R₂ -₁, then perform 2R ₂. 2 Perform the elementary row operation R₂ - 3₁. O First perform the elementary row operation R₂ - ₁, then perform 3R₂. O Perform the elementary row operation R₂ - ³₁. O First perform the elementary row operation R₂ - 2R₁, then perform 3R₂.
