\n" ); document.write( "-------------
\n" ); document.write( " $\"+4+%2F+%28+x+%2B+40+%29+=+.08+\"$
\n" ); document.write( " $\"+4+=+.08%2A%28+x+%2B+40+%29+\"$
\n" ); document.write( " $\"+4+=+.08x+%2B+3.2+\"$
\n" ); document.write( " $\"+.08x+=+4+-+3.2+\"$
\n" ); document.write( " $\"+.08x+=+.8+\"$
\n" ); document.write( " $\"+x+=+10+\"$
\n" ); document.write( "10 gallons of water must be added \n" ); document.write( "
