A bolt of cloth 100 yards long is cut into three pieces. The second piece is 15 yards longer than the first piece, and the length of the third piece is 5 yard more than twice the length of the first piece.

  1. PsyDAG

    x = first piece

    x+15 = second piece

    2x+5 = third piece

    x + (x+15) + (2x+5) = 100

    Solve for x, then others.
