Answer:

3n+2(n+2)=9n+12

3n+ 2n + 4 = 9n + 12

3n+ 2n +4 - 4 = 9n + 12 - 4

3n + 2n - 9n = 12 - 4

5n - 9n = 8

<u>-4n </u> = <u>8</u>

-4. -4

n. = - 2

I'm sorry I'm too lazy to read all of that. However, I did get the main point. The river was going at 3 mph. Since he wanted to travel 10 miles upstream and downstream, you would have to subtract 20 by 3. This would mean he was going at a speed of 17 mph.
