In words:
\n" ); document.write( "(salt)/(salt + water) = 25%
\n" ); document.write( "Let $\"a\"$ = gallons of 65% solution needed
\n" ); document.write( "Salt in 65% solution = $\".65a\"$
\n" ); document.write( "There is no salt in the pure water
\n" ); document.write( " $\".65a%2F%28a+%2B+8%29+=+.25\"$
\n" ); document.write( " $\".65a+=+.25%2A%28a+%2B+8%29\"$
\n" ); document.write( " $\".65a+=+.25a+%2B+2\"$
\n" ); document.write( " $\".4a+=+2\"$
\n" ); document.write( " $\"a+=+5\"$
\n" ); document.write( "5 gallons of 65% solution are needed \n" ); document.write( "

\n" );
