You can put this solution on YOUR website!
Let \"+x+\" = ml of solution B used
\n" ); document.write( "\"+x+-+300+\" = ml of solution A used
\n" ); document.write( "覧覧覧覧覧覧
\n" ); document.write( "\"+.19%2A%28+x+-+300+%29+=+alcohol+in+solution+A%0D%0A%7B%7B%7B+.12x+\" = alcohol in solution B
\n" ); document.write( "\"+377+\" = alcohol in solution A and B
\n" ); document.write( "覧覧覧覧覧覧
\n" ); document.write( "\"+.12x+%2B+.19%2A%28+x+-+300+%29+=+377+\"
