Answer:
27 gallons
Step-by-step explanation:
Our equation is:
What do we need to find: x
We need to first find x, so lets find x first.
=>
=>
=> x = 27
Lets go back to our equation.
We are going to simplify this before solving this. We are going to get:
=> 18 = 18
Therefore, we found x and we checked that our x value is correct. Now, we need to find how many gallons can the container can hold.
[a = gallons can the container hold]
=> x = a
Basically that means the container can hold 27 gallons of water.
