The property in the expression 4 + (x + y) = (4 + x) + y is Commutative property.
<h3>What is the number?</h3>
A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that:
4 + (x + y) = (4 + x) + y
As we know,
Commutative property is the property in which we can arrange the terms withouth changing the sign.
For an example:
a + b = b + c
In the given expression
4 + (x + y) = (4 + x) + y
The Commutative property is applied to rearrange the terms.
Thus, the property in the expression 4 + (x + y) = (4 + x) + y is Commutative property.

Step-by-step explanation:
Let T be the capacity of the tank.
Since the tank was 1/3 full and ends up 7/9 full.
T - T = 12
Simplifying the left side of the equation, tells us how much 12 gallons fills.
T = 12
Now we solve for T:
T = 12*9/4
T = 27
