If I add \"+x%2F2+%2B+12+\", that is how old
\n" ); document.write( "Alex is now
\n" ); document.write( "If I add \"+x%2F2+\" to that, He will be \"+2x+\" yrs old
\n" ); document.write( "\"+x%2F2+%2B+12+%2B+x%2F2+=+2x+\"
\n" ); document.write( "\"+x+%2B+12+=+2x+\"
\n" ); document.write( "\"+x+=+12+\"
\n" ); document.write( "------------
\n" ); document.write( "Right now, Alex is \"+x%2F2+%2B+12+\"
\n" ); document.write( "\"+12%2F2+%2B+12+=+18+\"
\n" ); document.write( "\"+3x+=+3%2A12+\"
\n" ); document.write( "\"+3x+=+36+\"
\n" ); document.write( "\"+18+%2B+36+=+54+\"
