Answer:
Step-by-step explanation:
How many units u move
The first equation is

The second equation is

If you sum the two equations you'll cancel y:

And since the sum must be 11, we have y=9.
Since the tank is 66.06% full, it is (100 - 66.06) = 33.94% empty.
Its capacity is 6,000L. So, in order to fill it to capacity, the service station
must order 33.94% of 6,000L .
33.94% = 0.3394
"of" means "times"
0.3394 x 6,000L = <em>2,036.4 liters</em> needed, to fill the tank to the rim.
All I can find on this is that it would be 10/16 but thats not an awnser. hmmm
