You can put this solution on YOUR website! a piece of wood is cut into 3 pieces the 2nd piece is 4 ft longer than the first piece, the 3rd piece is three times as long as the 1st piece but 5 ft shorter. if the board was 49ft long, find the length of each piece.
-----------------
1st piece:: x ft
2nd piece:: x+4 ft
3rd piece:: 3x-5 ft
--------
Equation::
x + x+4 + 3x-5 = 49
Combine like terms to get,
5x - 1 = 49
5x = 50
x = 10 ft (1st piece)
2nd piece:: x+4 = 14 ft
3rd piece:: 3x-5 = 30-5 = 25 ft
-----------------------------------
