document.write( "Let the son age will be x years.\r\n" );
document.write( "\r\n" );
document.write( "Then your age is (x+30) years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In three years . . . \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    (x + 30) + 3 = 3*(x+3).\r\n" );

document.write( "    x + 33 = 3x + 9\r\n" );
document.write( "\r\n" );
document.write( "    33 - 9 =  3x - x\r\n" );
document.write( "\r\n" );
document.write( "    24     = 2x\r\n" );
document.write( "\r\n" );
document.write( "      x    =  = 12.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus the son is 12 years old; you are 12+30 = 42 years old.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  You are 42 years old.\r\n" );
