\n" ); document.write( "
\r\n" );
document.write( "Let  \"x\"  be her age now.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then in 8 years her age will be (x+8) years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the other side, \"twice her present age\" is (2x), and \r\n" );
document.write( "\r\n" );
document.write( "\"3 years more than twice her present age\" is this value  (2x+3).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "According to the condition, these two values are equal\r\n" );
document.write( "\r\n" );
document.write( "    x + 8 = 2x + 3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is your equation, and you want to solve it to find x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Collect the terms with x in the right side, and collect the constant terms in the left side, like this\r\n" );
document.write( "\r\n" );
document.write( "    8 - 3 = 2x - x\r\n" );
document.write( "\r\n" );
document.write( "    5 = x,\r\n" );
document.write( "\r\n" );
document.write( "which gives you the answer: the girl is 5 years old now.\r\n" );

\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "    Let x be the age under the question.\r\n" );
