From eq. 1,
\n" ); document.write( "\"2x=6-4y\"
\n" ); document.write( "\"x=-2y%2B3\"
\n" ); document.write( "Substituting into eq. 2,
\n" ); document.write( "\"3%28-2y%2B3%29%2B6y-9=0\"
\n" ); document.write( "\"-6y%2B9%2B6y-9=0\"
\n" ); document.write( "\"0=0\"
\n" ); document.write( "True, but not actually yielding a solution.
\n" ); document.write( ".
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( "Eq. 1 is actually a multiple of eq. 2,
\n" ); document.write( "\"%283%2F2%29%282x%2B4y-6%29=%283%2F2%29%280%29\"
\n" ); document.write( "\"3x%2B6y-9=0\"
\n" ); document.write( "So, they are the same equation so there are infinitely many solutions.\r
