Let $\"+x+\"$ = distance from bottom of mirror to floor
\n" ); document.write( " $\"+x%2F2+\"$ = distance from top of mirror to ceiling
\n" ); document.write( " $\"+x%2F2+%2B+28.25+%2B+x++=+91.25+\"$
\n" ); document.write( " $\"+%283%2F2%29%2Ax+=+63+\"$
\n" ); document.write( " $\"+x+=+%282%2F3%29%2A63+\"$
\n" ); document.write( " $\"+x+=+2%2A21+\"$
\n" ); document.write( " $\"+x+=+42+\"$
\n" ); document.write( "The distance from bottom of mirror to floor is 42\"
