Answer:

33x + 92y

Answer 2

A. 33x + 92y

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.
