You can put this solution on YOUR website!
1.\"+++x+%2B++5y+=+++10\"
\n" ); document.write( "2.\"-+2x+-+10y+=+-+20\"
\n" ); document.write( "if you multiply both sides of equation 1 by -2,
\n" ); document.write( "1.\"++-2x+%2B++%28-10y%29=+++-20\"
\n" ); document.write( "you get equation 2.
\n" ); document.write( "These are dependent equations (the same equation).
\n" ); document.write( "
\n" );
