Hmmm... in order to be able to solve these type of expressions and more complex ones, we need to know what like terms are in the first place.

Let's see the terms that have the same exact variables! They are 3.26d and 9.75d.

By the way, before we continue--I would like to mention something extremely important: 3.26d and 9.75d are positive, whereas -2.65 is negative (you know, the negative sign appears right before it).

Now, let's add 3.26d and 9.75d. It equals 13.01d.
