The u terms can be combined with the u terms and the v terms can be combined with the v terms

Like this: 3u + 4u = 7u, and 7v - 2v = 5v

So the answer is 7u + 5v

Don't for get to only add like terms. Like terms have the same variable. The variable is the u or the v in this case.

Group the u terms: 3u + 4u = 7u

Group the v terms: 7v - 2v = 5v

Add them up: 3u+4u+7v-2v = 7u + 5v

Same answer as SupriseMe
