\n" ); document.write( "Add $\"R%5B2%5D\"$ and $\"R%5B3%5D\"$ and replace in $\"R%5B3%5D\"$ ,
\n" ); document.write( "

\n" ); document.write( "Replace $\"R%5B2%5D\"$ with $\"R%5B1%5D-3R%5B2%5D\"$ ,
\n" ); document.write( "

\n" ); document.write( "Replace $\"R%5B3%5D\"$ with $\"R%5B2%5D%2B5R%5B3%5D\"$ ,
\n" ); document.write( "

\n" ); document.write( "So then from $\"R%5B3%5D\"$ ,
\n" ); document.write( " $\"20x=40\"$
\n" ); document.write( " $\"x=2\"$
\n" ); document.write( "Then from $\"R%5B2%5D\"$
\n" ); document.write( " $\"-5%282%29%2B5y=-15\"$
\n" ); document.write( " $\"5y=-5\"$
\n" ); document.write( " $\"y=-1\"$
\n" ); document.write( "and then from $\"R%5B1%5D\"$ ,
\n" ); document.write( " $\"2%2B2%28-1%29%2B3z=9\"$
\n" ); document.write( " $\"3z=9\"$
\n" ); document.write( " $\"z=3\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
