Exercise 17 Page 212

Recall the Distributive Property.

11x-11y

Practice makes perfect

We want to simplify the given expression. To do it, we will use the Distributive Property. We will distribute 11 to the terms inside the parentheses.

11(x-y)

Distribute 11

11(x)-11(y)

Remove parentheses

11x-11y

Since 11x and 11y are not like terms, the expression cannot be simplified further.
