A.
33x + 92y
B.
47x + 92y
C.
47x + 24y
D.
33x + 24y

A. 33x + 92y

Step-by-step explanation:

Set up the problem like this and combine like terms:

    40x + 58y

   - 7x  + 34y

    33x + 92y

Or, set up the problem like this and combine like terms:

(40x + 58y) + (-7x + 34y)

40x + 58y - 7x + 34y

40x - 7x + 58y + 34y

33x + 92y

You should get the same answer with either method.
