\"w\"= age of the watercolor
\n" ); document.write( "Since the oil painting is 16 years older than a watercolor,
\n" ); document.write( "\"w%2B16\"= age of the oil painting.
\n" ); document.write( "Since the oil painting is also three times older than the watercolor,
\n" ); document.write( "\"3w\"= age of the oil painting, too.
\n" ); document.write( "So, \"3w=w%2B16\" .
\n" ); document.write( "Subtracting \"w\" from both sides of the equation, we get
\n" ); document.write( "\"3w-w=w%2B16-w\"
\n" ); document.write( "\"2w=16\"
\n" ); document.write( "\"w=16%2F2\"
\n" ); document.write( "\"highlight%28w=8%29\" .
\n" ); document.write( "The watercolor is \"highlight%288%29\" years old.
\n" ); document.write( "
\n" );
