Problem

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

2

Step

The given equation

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

3

Formula

Associative property of addition: a + (b + c) = (a + b) + c.

4

Step

Now simplify both sides using the associative property:

x + 7 = 9 + 4

x + 7 = 13

5

Step

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

x = 13 - 7

x = 6

6

Solution

Therefore, the value of x is 6.

8

Choice-A

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

Wrong 9

9

Choice-B

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

Wrong 7

10

Choice-C

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

Correct 6
