Use the Associative Property of Addition to find the value of a variable
x + (3 + 4) = (6 + 3) + 4.

The given equation

x + (3 + 4) = (6 + 3) + 4

Associative property of addition

a + (b + c) = (a + b) + c

Now simplify both sides using the associative property:

x + 7 = 9 + 4
x + 7 = 13

To solve for x, we subtract 7 from both sides:

x = 13 - 7
x = 6

Therefore, the value of x is 6.

This is incorrect because, when calculated, the value of x is 6, not 9

9

This is also incorrect. 7 is a part of the expression x + 7, not the value of x itself

7

This is the correct answer. We found that x equals 6 after solving the equation

6

This value does not satisfy the equation derived from the Associative Property of addition
