Consider the following Gauss-Jordan reduction: Find E₁ = E₂ = E3 = E₁ = | [1 0 -4] [1 0 ⠀⠀⠀⠀⠀ 0 0 1 0 1 0 E2E1A 1 0 -47 [1 0 -4 -7 0 1 0 0 27 → 70 -27 A 0 1 0 E₁A 0 1 0 0 1 E3E2E1A [1 →0 0 1 00 01 0 = I 1 E4E3E2E1A
Write A as a product A = E₁¹E₂¹E, ¹E₁¹ of elementary matrices: 1 -7 0 0-4 0 27 = 1 0
