Question 996262: A 20 foot board is cut into 3 pieces. Two are the same length. One piece is 2 feet longer than the other pieces. How long are the pieces? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call the equal pieces length x.
The longer piece is x + 2.
The three pieces added are
x + x + (x+2) = 20
3x + 2 = 20
3x = 18
x = 6
So the pieces are 6, 6, and 8.
