Ex 4.6, 3 Examine the consistency of the system of equations. x + 3y = 5 2x + 6y = 8 x + 3y = 5 2x + 6y = 8 Writing equation as AX = B [β 8(1&3@2&6)] [β 8(π₯@π¦)] = [β 8(5@8)] Hence A = [β 8(1&3@2&6)] , X = [β 8(π₯@π¦)] & B = [β 8(5@8)] Calculating |A| |A| = |β 8(1&3@2&6)| = 1(6) β 2(3) = 6 β 6 = 0 Since |A| = 0, we will calculate (adj A) B A = [β 8(1&3@2&6)] adj (A) = [β 8(1&3@2&6)] = [β 8(6&β3@β2&1)] Now, (adj A)(B) = [β 8(6&β3@β2&1)] [β 8(5@8)] = [β 8(6(5)+(•7β3)8@β2(5)+1(8))] = [β 8(30β24@β10+8)] = [β 8(6@β2)] β O Since adj A (B) β O & |A| = 0, , There exists no solution, Hence, the given system of equation is inconsistent
