document.write( "2x +  5y = 4,    (1)\r\n" );
document.write( "4x + 10y = 1.    (2)\r\n" );
document.write( "\r\n" );
document.write( "Multiply the first equation by 2 (both sides). You will get an equivalent system\r\n" );
document.write( "\r\n" );
document.write( "4x + 10y = 8,    (1')\r\n" );
document.write( "4x + 10y = 1.    (2')\r\n" );
document.write( "\r\n" );
document.write( "These equations have identical left sides, but different right sides.\r\n" );
document.write( "\r\n" );
document.write( "It implies, that the system (1'),(2') has no solutions.\r\n" );
