Let John’s age be J
\n" );
document.write( "Then Mary’s is: 32 – J
\n" );
document.write( "We then get: J – 4 = 2(32 – J – 4)
\n" );
document.write( "J – 4 = 2(28 – J)
\n" );
document.write( "J – 4 = 56 – 2J
\n" );
document.write( "J + 2J = 56 + 4
\n" );
document.write( "3J = 60
\n" );
document.write( "J, or John is: 
\n" );
document.write( "Mary is:  \n" );
document.write( "

\n" );
