Explanation Given: The given system of equations are 17 x − 22 y − 19 z = − 25.2 3 x + 13 y − 9 z = 105.9 x − 2 y + 6.1 z = − 23.55 It can be written in matrix form A= [ 17 − 22 − 19 3 13 − 9 1 − 2 6.1 ] B= [ − 25.2 105.9 − 23.55 ] X= [ x y z ] A X = B s o X = A − 1 B Key concept: A matrix A is invertible, i.e., the inverse of the matrix A is exist if the matrix A is non–singular, i.e., the determinant of the matrix A is not equal to zero. Formula Used: A − 1 = a d j A | A | ; a d j A = [ C 11 C 21 C 31 C 12 C 22 C 32 C 13 C 23 C 33 ] and C i j is the cofactor of the element a i j of the matrix A , i .e . , C i j = ( − 1 ) i + j M i j , where M i j is the minor of the element a i j of the matrix A . Calculation : Now calculate the determinant value of A A= | 17 − 22 − 19 3 13 − 9 1 − 2 6.1 | | A | = 17·13·6.1 + (–22)·(–9)·1 + (–19)·3·(–2) – (–19)·13·1 – 17·(–9)·(–2) – (–22)·3·6.1 = 1348.1 + 198 + 114 + 247 – 306 + 402.6 =2003.7 = 20037/10 Thus, the matrix A is non-singular and hence invertible, i.e., A –1 exist. To calculate the inverse of matrix A , we need to find minors and cofactors of matrix А . • Find the minor M 11 and the cofactor C 11 . In matrix A cross out row 1 and column 1. M 11 = | 13 − 9 − 2 6.1 | = 13 · 6.1 − ( − 2 ) · ( − 9 ) = 79.3 − 18 = 61.3 C 11 = (–1) 1+1 M 11 = 61.3 • Find the minor M 12 and the cofactor C 12 . In matrix A cross out row 1 and column 2. M 12 = | 3 − 9 1 6.1 | = 3 · 6.1 − 1 · ( − 9 ) = 18.3 + 9 = 27.3 C 12 = (–1) 1+2 M 12 = –27.3 • Find the minor M 13 and the cofactor C 13 . In matrix A cross out row 1 and column 3. M 13 = | 3 13 1 − 2 | = 3 · ( − 2 ) − 1 · 13 = − 6 − 13 = − 19 C 13 = (–1) 1+3 M 13 = –19 • Find the minor M 21 and the cofactor C 21 . In matrix A cross out row 2 and column 1. M 21 = | − 22 − 19 − 2 6.1 | = ( − 22 ) · 6.1 − ( − 2 ) · ( − 19 ) = − 134.2 − 38 = − 172.2 C 21 = (–1) 2+1 M 21 = 172.2 • Find the minor M 22 and the cofactor C 22 . In matrix A cross out row 2 and column 2. M 22 = | 17 − 19 1 6.1 | = 17 · 6.1 − 1 · ( − 19 ) = 103
