and this problem. We're being asked to perform the given operation for this particular problem or being asked to add two to Paulino meals. And the reason why we know that because there's a plus sign in between the two sets of preface is, Well, how do we add Paulino meals? Well, we're going to use the community of an associative properties to regroup and reorder our terms. So that way are late. Terms are together. So let's look at our first term to why it has a late term of four. Why? So we can group these two terms together so we'll have the quantity of two. Why plus four way? Well, our next term is negative three, which has a light term, a positive seven so weakened group these terms together as well, so we'll have, plus the quantity of negative three plus seven. Now we simply need to combine our light terms. So let's first look at our first set of parentheses, where we have to y plus four y, while two plus four is equal to six, so we'll have six why. And in our second set of prophecies, we have negative three plus seven, which is four. So we'll have plus four. So our final answer is six y plus four
