Answer:

Step-by-step explanation:
step 1
Find the volume of the tank

step 2
we know that
If the tank is 1/3 full of water
then
the volume of water required to completely fill the tank is equal to 2/3 of the tank capacity
so

The only thing you should do is to multiply 7 by 2x and 10.
so you will have: (7*2x) + (7*10) = 14x + 70 :)))
