You can put this solution on YOUR website!
Let x +6 = original number of kids. So x = remaining number of kids after 6 left.\r
\n" ); document.write( "\n" ); document.write( "Then \"1800%2Fx+-+1800%2F%28x%2B6%29+=+10\",
\n" ); document.write( "or
\n" ); document.write( "\"180%2Fx+-+180%2F%28x%2B6%29+=+1\", or
\n" ); document.write( "\"0+=+x%5E2+%2B+6x+-+1080\", after simplification.
\n" ); document.write( "(x-30)(x+36) = 0.
\n" ); document.write( "Thus there are x = 30 kids going to the trip.
\n" ); document.write( "
\n" );
