Lets say there are x balls So, Number of blue balls = x-4 Number of green balls = x-4 Number of red balls = x-4 Total number of balls = 3x-12 But we took the original number of balls to be x. Therefore, 3x-12=x or, x=6

In that case, there could be 1 blue, 1 green, 1 red, and 2 of other colors (say black and white). Using einsteinager's math, this would look like: Let x = total number of balls Number of blue balls = x-4 Number of green balls = x-4 Number of red balls = x-4 Number of other colored balls = y x = 3(x - 4) + y x = 3x - 12 + y 2x = 12 - y The only restriction on y is that it cannot be greater than x. Values of y that produce positive integer results for x, with x >= y are: y = {0, 2, 4} Thus, there could be 2 other colored balls, and a total of 5 balls. You could even logically say that there could be 4 balls of other colors, and no blue/green/red balls. If the problem were to state that the bag only has blue, green, and red balls, then y would be 0, and the answer would be 6.
