\n" ); document.write( "John is 3 years older than Mary. Five years ago he was four times as old as Mary was then. How old is John?
\n" ); document.write( "

Let John's age be J
\n" );
document.write( "Then Mary's is: J - 3
\n" );
document.write( "We then get: J - 5 = 4(J - 3 - 5)
\n" );
document.write( "J - 5 = 4(J - 8)
\n" );
document.write( "Continue to solve for J, John's current age. \n" );
document.write( "

\n" );
