So what you would basically do is combine the like-terms. In order to do that you would first locate the variables that are alike, for example if you have 4x + 6y + 8x - 2y , you would add the two numbers that end with x and get 12x, and then you would add the two numbers that end with y and get 4y.
In this case the answer would be:
D. 11u + 4v
because you would add the numbers that end in u together and add the numbers that end in v together.
