Each matrix in an equation of the form AX=B has a name
\n" ); document.write( "Coefficient matrix A Vaiable Matriz X Constant Matrix B
\n" ); document.write( "2 1 -1 x 5
\n" ); document.write( "3 -1 2 * y = -1
\n" ); document.write( "1 -1 -1 z 19
\n" ); document.write( "IT MEANS ASSUMING SOME POSSIBLE TYPOS IN YOUR PROBLEM
\n" ); document.write( "2X+1Y-1Z = 5..............................I
\n" ); document.write( "3X-1Y+2Z = -1..............................II
\n" ); document.write( "1X-1Y-1Z = 19...................................III \r
\n" ); document.write( "
