Matrix
By Gauss-Jordan method ,show that following system has no soloution. x+2y-3z=-13,x-y+2z=7,x+3y-4z=2 A={{1,2,-3,-1},{3,-1 ,2,7},{5,3,-4,2}}//MatrixForm RowReduce[{{1,2,-3,-1},{3,-1 ,2,7},{5,3,-4,2}}]//MatrixForm From the equation, we can write,1x+1/7z=0,1y-11/7z=0,0=1; So,we can say that This equation has no solution. Thank You😊
