There is nothing in the description you have given which tells us the amount of that unspecified number, therefore, the answer could be anything. If you want to solve for an unknown number you need an equation. You might have said four times a number added to -9 subtracted from triple the sum of nine times the number and eight is equal to zero. Then we can solve the equation.

Let the number be x: 3x-9 = 45 3x = 45+9 3x = 54 x = 18

After four months, the number of rabbits will triple to 3 x 3 = 9. After 8 months, the number will triple again to 9 x 3 = 27. After 12 months, the number will triple one more time to 27 x 3 = 81 rabbits.

One of many generalised answers is {9-x, 9, 9+x} where x is any non-negative real number. So, one possible triple (x = 0) is {9, 9, 9}. Another (x=17) is {-8, 9, 26}.
