The notes that I have aren't helping me much.

First problem:
A 9-foot board is cut into two pieces so that one piece is 5 feet longer than three times the shorter piece. Find the length of both pieces.

Second problem:
The number of women attending a math class was 9 less than twice the number of men. If a total of 63 students attended the class, how many were women?

I do remember doing these problems back in high school, but for some reason these are the only math problems I have trouble with! Any help is GREATLY appreciated. Thanks!
