= ∆1=70

=∆2=749

=∆3=490

=∆4=-168 x1=∆1/∆=2; x2=21.4; x3=14; x4=-4.8

7. Tenglamalar sistemasini teskari matritsa usulida yeching: Ax=B



a) X= B= X=A-1×B

A-1= = 1; A11=-3; A12=0; A13=-4; A21=2; A22=1; A23=3; A31=-3; A32=-2; A33=-5



Agebraik to’ldiruvchilardan matritsa yasaymiz: endi buni transponerlaymiz:

Bu matritsaga dastlabki matritsaning determinantini teskari ko’paytirishimiz kerak, lekin bu matritsada determinant 1 bo’lgani uchun bu qadam shart emas.
