In a subtraction formula, the sum of the subtracted, the subtracted and the difference is 160, and the difference is three fifths of the subtracted. What is the subtraction formula? 2. It is known that the sum of the subtracted, the subtracted and the difference is 58, and the subtracted is () (fill in the blanks) 3. In a subtraction formula, the difference is 15. If the subtracted remains unchanged, the subtraction increases by 5.6, and the difference is ()

If the subtracted remains unchanged, the subtraction increases by 5.6, and the difference is ()

1. Let the subtracted be x, y and Z, respectively
x-y=z
x+y+z=160
3/5y=z
From the solution of the above three formulas, we get x = 80, y = 50, z = 30
2. The solution is the same as above
x-y=z
x+y+z=58
The solution is x = 29
3. If the subtracted is unchanged and the subtracted is increased by 5.6, the difference should be reduced by 5.6, so the difference is 15-5.6 = 9.4

In a subtraction formula, the sum of the subtracted, the subtracted and the difference is 240. The subtracted is three times the difference. What's the difference

The subtraction is three times the difference, which means that the sum of subtraction and difference is four times, plus the subtracted is eight times
Double = 240 / 8 = 30
So, difference = 30
Subtraction = 90
Subtracted = 120

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
