Simplify the following expression.

(70x + 59y) + (-6x + 33y)
A.
64x + 92y
B.
64x + 26y
C.
76x + 92y
D.
76x + 26y

To simplify the expression, combine like terms:

(70x + 59y) + (-6x + 33y)

Combine the x terms:
70x + (-6x) = 70x - 6x = 64x

Combine the y terms:
59y + 33y = 92y

So the simplified expression is:
64x + 92y

The correct answer is A. 64x + 92y.
