If I am using the Gauss-Jordan elimination method then the next row operation for these problems should be?
\n" ); document.write( "1.
\n" ); document.write( "{1 2 -1 | 6}
\n" ); document.write( "{0 -2 2 | 6}
\n" ); document.write( "{0 2 -4 |-4}
\n" ); document.write( "Add R2 to R3
\n" ); document.write( "----------------------
\n" ); document.write( "2.
\n" ); document.write( "{1 1 -1| 6}
\n" ); document.write( "{0 -2 2| 6}

\n" ); document.write( "Add R2 to R3
