\n" ); document.write( "\n" ); document.write( "        In his post, @consc198 solves inequality 7-3x < 31.\r
\n" ); document.write( "\n" ); document.write( "        He did it FUNDAMENTALLY WRONG.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        For correct solution to this inequality see what follows.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "7 - 3x < 31.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Move 3x to the right side, changing the sign.\r\n" );
document.write( "\r\n" );
document.write( "Move 31 to the left side, changing the sign.\r\n" );
document.write( "\r\n" );
document.write( "You will get an equivalent inequality\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    7 - 31 < 3x,\r\n" );
document.write( "\r\n" );
document.write( "      -24  < 3x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Divide both sides by 3\r\n" );
document.write( "\r\n" );
document.write( "      -8   < x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The solution to inequality  7-3x < 31  is the set of real numbers  x > -8.\r\n" );
document.write( "

\n" ); document.write( "\n" ); document.write( "As this person, @consc198, solves simple standard Math problems, he deserves to be excluded
