\n" ); document.write( "Fred is 8 years older than frank . Francis is 3 years younger than Fred . If the sum of their ages is 40 , find the age of each child
\n" ); document.write( "

Let Fred's age be F
\n" );
document.write( "Then Frank's is: F - 8
\n" );
document.write( "Francis' is: F - 3
\n" );
document.write( "We then get: F + F - 8 + F - 3 = 40
\n" );
document.write( "Solve for F, Fred's age, and find the others' ages. \n" );
document.write( "
