Write an equivalent expression. Use an associative law.

(x + 5) + y

x + (5+y)

To write an equivalent expression using the associative law, we need to rearrange the terms by grouping them differently.

The associative law states that for any three numbers a, b, and c, the sum (a + b) + c is equivalent to a + (b + c).

In this case, we have (x + 5) + y. To apply the associative law, we can group the terms differently by associating x with y instead of x with 5.

So, (x + 5) + y can be rewritten as x + (5 + y).

Therefore, x + (5 + y) is the equivalent expression using the associative law.
