\n" ); document.write( "Aaron is four more than one-half as old as Hunter. Kevin is thirty-one less than four times the age of Aaron. In five years, Kevin will be twenty-five less than three times the age of Aaron. How old is Kevin?
\n" ); document.write( "

Hunter has absolutely nothing to do with this problem, so info about him is excessive and unnecessary.
\n" );
document.write( "Let Aaron's age be A, and Kevin's, K
\n" );
document.write( "Then K = 4A - 31
\n" );
document.write( "We're also given that: K + 5 = 3(A + 5) - 25 =====> K + 5 = 3A + 15 - 25
\n" );
document.write( "K = 3A - 15
\n" );
document.write( "We then get: 4A - 31 = 3A - 15
\n" );
document.write( "4A - 3A = 16
\n" );
document.write( "A, or Aaron is: 16 years-old
\n" );
document.write( "Kevin is:  \n" );
document.write( "

\n" );
