To use the Associative Property to show that Expression 1 is equivalent to Expression 2, we need to group the terms in Expression 2 in a different way.
Expression 2: 15x + (8x - 7) - 11
Now let's group the terms differently using parentheses:
Expression 2: (15x + (8x - 7)) - 11
By doing this, we are associating the term (8x - 7) with the term (15x), which allows us to apply the Associative Property.
Now let's simplify the expression within the parentheses:
Expression 2: (15x + 8x - 7) - 11
Combining like terms within the parentheses:
Expression 2: 23x - 7 - 11
Simplifying further:
Expression 2: 23x - 18
We can see that Expression 2 has been transformed into Expression 1 by using the Associative Property.
