Initially, a tank is 1/4filled with water. After adding 5 gallons of water, tank become 2/3 full. what is the capacity of the tank in gallons?

For your kind information answer is 12 but I want solution

​

Answer 1

Let T = the number of gallons the tank can hold.

Your equation becomes

1/4 T + 5 = 2/3 T

5 = 2/3 T - 1/4 T

5 = 8-3/12

5 = 5/12

1= 5/12× 1/5

=12

So the capacity of the tank in the gallons is =12

hope this may helps you.!
