1. $\"x-+2y+%2B+z+=+4\"$
\n" ); document.write( "2. $\"y+%2B+6z+=-1\"$
\n" ); document.write( "3. $\"z+=+2\"$
\n" ); document.write( "Back substitute from eq. 3 into eq. 2,
\n" ); document.write( " $\"y%2B6%282%29=-1\"$
\n" ); document.write( " $\"y%2B12=-1\"$
\n" ); document.write( " $\"y=-13\"$
\n" ); document.write( "Now into eq. 1,
\n" ); document.write( " $\"x-2%28-13%29%2B2=4\"$
\n" ); document.write( " $\"x%2B26%2B2=4\"$
\n" ); document.write( " $\"x=-24\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
