You can put this solution on YOUR website!
Let \"+w+\" = gallons of water to be added
\n" ); document.write( "\"+.7%2A30+=+21+\" = gallons of antifreeze in 70% solution
\n" ); document.write( "------------------
\n" ); document.write( "\"+21+%2F+%28+w+%2B+30+%29+=+.6+\"
\n" ); document.write( "\"+21+=+.6%2A%28+w+%2B+30+%29+\"
\n" ); document.write( "\"+21+=+.6w+%2B+18+\"
\n" ); document.write( "\"+.6w+=+3+\"
\n" ); document.write( "\"+w+=+5+\"
\n" ); document.write( "5 gallons of water must be added
\n" ); document.write( "----------------
