Let x is Joe's age now
\n" ); document.write( "In 8 years Joe will be \"%28x%2B8%29\" years old
\n" ); document.write( "4 years ago Joe was \"%28x-4%29\"
\n" ); document.write( "In 8 years Joe will be twice the age he was 4 years ago, so \"x%2B8=2%28x-4%29\"
\n" ); document.write( "\"x%2B8=2x-8\"
\n" ); document.write( "\"x-2x=-8-8\"
\n" ); document.write( "\"-x=-16\"divide by -1
\n" ); document.write( "\"x=16\"
\n" ); document.write( "Answer 2=16
\n" ); document.write( "
