\n" ); document.write( "The amount of acid in liters is:
\n" ); document.write( " $\"+.35%2A100+=+35+\"$ liters
\n" ); document.write( "---------------------
\n" ); document.write( "Let $\"+w+\"$ = liters of water to be added
\n" ); document.write( " $\"+35+%2F+%28+100+%2B+w+%29+=+.1+\"$
\n" ); document.write( " $\"+35+=+.1%2A%28+100+%2B+w+%29+\"$
\n" ); document.write( " $\"+35+=+10+%2B+.1w+\"$
\n" ); document.write( " $\"+.1w+=+25+\"$
\n" ); document.write( " $\"+w+=+25%2F.1+\"$
\n" ); document.write( " $\"+w+=+250+\"$
