  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😊

 Today I will write about Math Lab.Math Lab is very important in mathematics.Today's blog will show the experiments of Matrix.So let's get started Matrix: Suppose (1,2) and (3,4) are the two components of the matrix. Then the matrix structure will be:       A={{1,2},{3,4}}//MatrixForm    TagBox[RowBox[{"(", "\:2060", GridBox[{{ItemBox["1"], ItemBox["2"]}, {ItemBox["3"], ItemBox["4"]}}, RowSpacings -> 1, ColumnSpacings -> 1, RowAlignments -> Baseline, ColumnAlignments -> Center], "\:2060", ")"}], Function[BoxForm`e$, MatrixForm[BoxForm`e$]]] Again the transpose matrix will be - Trans=Transpose[{{1,2},{3,4}}]//MatrixForm TagBox[RowBox[{"(", "\:2060", GridBox[{{ItemBox["1"], ItemBox["3"]}, {ItemBox["2"], ItemBox["4"]}}, RowSpacings -> 1, ColumnSpacings -> 1, RowAlignments -> Baseline, ColumnAlignments -> Center]...
