You can put this solution on YOUR website!
Let \"+x+\" = ml of solution B
\n" ); document.write( "\"+2x+\" = ml of solution A
\n" ); document.write( "覧覧覧覧覧覧覧覧
\n" ); document.write( "\"+.11%2A2x+%2B+.2x+=+84+\"
\n" ); document.write( "\"+.22x+%2B+.2x+=+84+\"
\n" ); document.write( "\"+.42x+=+84+\"
\n" ); document.write( "\"+x+=+200+\"
\n" ); document.write( "He uses 200 ml of solution B
\n" ); document.write( "
