Answer:
x + x+5 = 20
2x + 5 = 20
2x = 15
x =7.5 and
x + 5 = 12.5
The pieces are 7.5 and 12.5 feet long.

EDITED ANSWER I mistyped the equation. The 20 foot board is cut into two pieces so that the second piece is 5 feet longer than twice the length of the first piece how long is the first piece
x + (2x +5) = 20
3x +5 = 20
3x = 15
x = 5 feet
Second board is twice as long as shorter board plus 5 feet.
Second board = 2 * 5 + 5 which equals 15
The boards are 5 and 15 feet in length.
