9mph is the boat's actual speed.
12mph with the stream and 6mph against the stream.
12mph takes 2 hours to get there and 6mph takes 4 to get back = 6hours.

None of the listed expressions are equivalent

4(n – 32) + n = 5n - 128

Step-by-step explanation:

4(n – 32) + n

Distribute the 4

(4 * n - 4 * 32) + n

(4n - 128) + n

Combine like terms

5n - 128
