Answer 3

3 + (4 + 7) = (3 + 7) + 4

To solve this equation, we can use the associative property of addition, which states that the grouping of numbers being added does not affect the sum. Therefore, we can rearrange the numbers within the parentheses without changing the result.

Starting with the left side of the equation: 3 + (4 + 7) = 3 + 11 = 14

Now let's solve the right side of the equation: (3 + 7) + 4 = 10 + 4 = 14

As you can see, both sides of the equation evaluate to 14. Therefore, the equation is true.
