Blueberries and Cups Puzzle

The number of blueberries is equal to number of cups multiplied by 4 minus one left.
That is :
      B = 9(C - 2) -> (1)
Then the number of blueberries will be equal to the number of cups times three plus one left.
That is :
      B = 6C + 3 -> (2)
Now substitute the 1st and 2nd equations:
      B = 9(C - 2)
      B = 6C + 3
      C = 7, B = 45.
Therefore Blueberries = 45 and cups = 7.

Maria have some blueberries and some cups. If she put 9 blueberries into each cup she will have two cups left. If she put 6 blueberries into each cup she will have three blueberries left over.
