Remember, when there is a subtraction outside of a group, you should add the opposite of each member. That is:

That is a bit confusing, so let's simplify. When you add a negative, you subtract:

Now, group your like variables:

Finally, perform the subtractions and get:

First distribute the subtraction sign through the terms in the parentheses.

Subtraction of a negative is the same as adding a positive.

Rewrite.

Group all like terms together.

Evaluate the terms in each parentheses.

Rewrite in simplest form.
