Add the subtracted, subtracted and difference of a subtraction formula to get 880. It is known that the subtracted is three times the difference. What is the subtracted? Concrete arithmetic process

Let the difference be x, then the subtraction = 3x and the subtracted = x + 3x = 4x
4x+3x+x=880
8x=880
x=110
Subtraction = 3 * 110 = 330
The subtraction is three times the difference
Subtracted - subtracted = difference
The subtracted is four times the difference
Subtracted + subtracted + difference = 4 * difference + 3 * difference + difference = 880
Difference = 880 / 8 = 110
The subtraction is 3 * 110 = 330
