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.
