Do some logical analysis before you plunge into the algebra, to make the problem easier!

\n" ); document.write( "If the sum of their current ages is 100, then 16 years ago that sum was 68.
\n" ); document.write( "If 16 years ago Bob was three times as old as Carol, then
\n" ); document.write( "\"x%2B3x+=+68\"
\n" ); document.write( "\"4x=68\"
\n" ); document.write( "\"x=17\"

\n" ); document.write( "16 years ago, Carol was x=17 and Bob was 3x=51.
\n" ); document.write( "When Carol was born, Bob was 51-17 = 34.
\n" ); document.write( "
