sir,if (adj A)B=0 then how we will find that it has infinite number of solutions or no solution??? Share with your friends Share 0 Lovina Kansal answered this Dear student If Adj.A.B=0, the system is consistent and has infinite number of solution.if Adj.A.B≠0, the system has no solution and is therefore inconsistent.To get the Solution of Linear Equations by the Matrix Method, we proceed as follows:If the given system is,a1x+b1y+c1z=d1; a2x+b2y+c2z=d2; a3x+b3y+c3z=d3Step1. Write the above system in the form of AX=Bwhere A is the coefficient matrix i.e., A=a1b1c1a2b2c2a3b3c3,X=xyz and B=d1d2d3Step2: Find A.Step 3: If A≠0, then given system has unique solution and X can be obtained by using the relationX=A-1B and if A=0, then conclude that system has no unique solution.Step4: When A≠0, Evaluate A-1 by using relation A-1=adjAA.Step 5: Evaluate x,y,z by relation X=A-1B. 0 View Full Answer
