A wooden railing is 82 feet long. It is to be divided into 4 pieces. Three pieces will be the same length, and the fourth piece will be 2 feet longer than each of the other three. Find the length of each piece.

3x + x + 2 = 82
4x = 80
x = 20
Three pieces are 20 feet each. One piece is 22 feet long.
