In a subtraction formula, the sum of the subtracted, the subtracted and the difference is 240. If the subtracted is five times the difference, what is the subtraction?

Let the difference of this formula be X. from the meaning of the question, we can get: x + 5x + 5x + x = 240 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 12x = 240 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 20, 20 × 5 = 100. A: the subtraction is 100
