john is older than his cousin bill.
\n" ); document.write( "j > b
\n" ); document.write( "-------------------
\n" ); document.write( "bill's age is 3 years more than one half the age of john.
\n" ); document.write( "b = (1/2)j + 3
\n" ); document.write( "------\r
\n" ); document.write( "\n" ); document.write( "if the difference in their ages is less than four years
\n" ); document.write( "j - b < 4
\n" ); document.write( "-------------------\r
\n" ); document.write( "\n" ); document.write( "What is the oldest that john can be in whole number of years?
\n" ); document.write( "---
\n" ); document.write( "Substitute for \"b\" and solve for \"j\":
\n" ); document.write( "j - [(j/2)+3] < 4
\n" ); document.write( "(1/2)j -3 < 4
\n" ); document.write( "(1/2)j < 7
\n" ); document.write( "j < 14 yrs (John is less than 14 so the oldest John can be is 13).
