or be asked to perform the giving operations. While for this particular problem, we're being asked to add the two palling appeals. And we know this because in between both sets of prophecies, there's a plus side. Well, how do we add Paulino meals? Well, we're going to use the community of an associate of properties to regroup and reorder our terms so that way are like terms will be together. So let's look at our first term of three X. It's like term is for X. So Beacon group these together as the quantity of three X plus four X. Our next term is seven. Well, it has a late term of negative three, so we can group these terms together. So we'll have, plus the quantity of seven minus three. Now we simply need to combine like terms. So let's look at our first set of prophecies. We have three x plus four x well, three plus +47 So we'll have seven X In our second percent of parentheses. We have seven minus three, which is four. So what? Plus four. So our final answer is seven x plus four
