Eliza was fixing a jigsaw puzzle. After three days, the number of pieces she fixed was 1/3 of the number of pieces she unfixed. After another week, she managed to fix another 20 pieces and was left with 3/5 of the puzzle unfixed. How many pieces were there in the puzzle?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

All pieces of the puzzle are **"****unfixed"!!!**

**x - (x/3 + 20) = 3/5x**

**x = 300**
