Unformatted text preview: Remark 2: Let us check that ± 21 ² is indeed a solution, in all three points of view on linear systems. As a system of linear equations: ( (2)(1) = 3 4(2) + 3(1) = 5 . As a matrixvector equation: ± 11 4 3 ²± 21 ² = ± 3 5 ² . As a vector equation: 2 ± 1 4 ²1 ±1 3 ² = ± 2 8 ² + ± 13 ² = ± 3 5 ² . 1...
