Let $\"+x+\"$ = gallons of water to be added
\n" ); document.write( " $\"+.8%2A8+=+6.4+\"$ gallons of boric acid in 80% solution
\n" ); document.write( " $\"+6.4+%2F+%28+x+%2B+8+%29+=+.5+\"$
\n" ); document.write( " $\"+6.4+=+.5%2A%28+x+%2B+8+%29+\"$
\n" ); document.write( " $\"+6.4+=+.5x+%2B+4+\"$
\n" ); document.write( " $\"+.5x+=+6.4+-+4+\"$
\n" ); document.write( " $\"+.5x+=+2.4+\"$
\n" ); document.write( " $\"+x+=+4.8+\"$
\n" ); document.write( "4.8 gallons of water must be added
\n" ); document.write( " \n" ); document.write( "
