\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " It is a standard and typical linear equation in one unknown \r
\n" ); document.write( "\n" ); document.write( " for a beginner student to start learning the subject.\r

\r\n" );
document.write( "The standard mantra to solve is as follows:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    subtract '30' from both sides.  You will get\r\n" );
document.write( "\r\n" );
document.write( "        45x = 120-30,\r\n" );
document.write( "\r\n" );
document.write( "        45x = 90.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     Now divide both sides by 45.  You will get\r\n" );
document.write( "\r\n" );
document.write( "         x =  = 2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     ANSWER.  The solution to given equation is  x = 2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     CHECK.  We substitute x= 2 into the left side of the given equation.  It gives the value \r\n" );
document.write( "\r\n" );
document.write( "                       45*2 + 30 = 90 + 30 = 120,\r\n" );
document.write( "\r\n" );
document.write( "                    the same as the right side of the given equation.\r\n" );
document.write( "\r\n" );
document.write( "                    This check CONFIRMS that the solution x = 2  is  CORRECT.\r\n" );
