Natasha2012 [34]

Answer: 18 gallons.

Step-by-step explanation:

Let's call the total gallons that the container can hold <em>x.</em>

<em> </em>Then, based on the information given in the problem, you can write the following expression:

$\frac{4}{9}x+4=\frac{2}{3}x$

Now, you must solve for x, as you can see below. Therefore, you obtain the following result:

$\frac{4}{9}x+4=\frac{2}{3}x\\\\4=\frac{2}{3}x-\frac{4}{9}x\\\\4=\frac{2}{9}x\\\\4*9=2x\\\\36=2x\\\\x=18\ gallons$
