\n" ); document.write( "Tom is twice as old as Andy. In 4 years time the sum of the ages will be 32 years. Find Andy’s present age.
\n" ); document.write( "

In 4 years, their ages sum to 32, so now, their ages sum to 32 - 2(4), or 32 - 8 = 24
\n" );
document.write( "Let Andy's be A
\n" );
document.write( "Then Tom's is 2A
\n" );
document.write( "We then get: A + 2A = 24
\n" );
document.write( "3A = 24
\n" );
document.write( "Andy, or  \n" );
document.write( "

\n" );
