An equivalent expression using the associative property 2+(11+y) can be written as (2+11)+y.

What is an Associative property?

The associative property states that the addition of the sum of two numbers (a,b) and a third number(c) is equal to the addition of the sun of the last two numbers(b, c) and the first number(a).

A+(B+C) = (A+B)+C

As the expression that is given to us is 2+(11+y), therefore, an expression that is equivalent to 2+(11+y) using the associative property can be written as,

[tex]2+(11+y) = (2+11)+y[/tex]
