\n" ); document.write( "james is 4 years less than 7 times the age of his daughter,who is 4 more than half of her brothers age. the sum of their ages is 38. How old is James?
\n" ); document.write( "

Let daughter's age be D\r\n" );
document.write( "Then James' age is 7D - 4\r\n" );
document.write( "Also, daughter's age, or \r\n" );
document.write( "\r\n" );
document.write( "Since all ages sum to 38, we get: D + 7D - 4 + 2D - 8 = 38\r\n" );
document.write( "10D - 12 = 38\r\n" );
document.write( "18D = 50\r\n" );
document.write( "Daughter's age, or \r\n" );
document.write( "James' age: 7(5) - 4 = 35 - 4 = 31

\n" ); document.write( "
