Let \"+w+\" = ounces of water to be added
\n" ); document.write( "given:
\n" ); document.write( "\"+.15%2A20+=+3+\" ounces of alcohol in 15% solution
\n" ); document.write( "-------------
\n" ); document.write( "\"+3+%2F+%28+20+%2B+w+%29+=+.1+\"
\n" ); document.write( "\"+3+=+.1%2A%28+20+%2B+w+%29+\"
\n" ); document.write( "\"+3+=+2+%2B+.1w+\"
\n" ); document.write( "\"+.1w+=+1+\"
\n" ); document.write( "\"+w+=+10+\"
\n" ); document.write( "10 ounces of water should be added
\n" ); document.write( "check:
\n" ); document.write( "\"+3+%2F+%28+20+%2B+w+%29+=+.1+\"
\n" ); document.write( "\"+3+%2F+%28+20+%2B+10+%29+=+.1+\"
\n" ); document.write( "\"+3+%2F+30+=+.1+\"
\n" ); document.write( "\"+.1+=+.1+\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
