In a subtraction formula, the subtracted is 48, the subtracted is 3 / 5 of the difference, and the subtracted is?

In a subtraction formula, the subtracted is 48, the subtracted is 3 / 5 of the difference, and the subtracted is?

Poor: 48 (1 + 3 / 5) = 30
Subtraction: 48-30 = 18

In a subtraction formula, the sum of the subtracted, the subtracted and the difference is 120, and the difference is three times that of the subtracted. The difference is ()
Let the subtracted be x, the subtracted be y, and the difference be 3Y
（120-y-3y)-y=3y
120-5y=3y
120=5y-3y
y=120/2
y=60
60=y+3y
60=4y
60/4=y
15=y
15*3=45
(is that right? No, help me explain it. Be more detailed.) well done, there are bonus points

120-5y=3y
120=5y-3y
It's wrong here
It should be 120 = 5Y + 3Y
120=8y
y=15
3y=45
So the difference is 45
60=y+3y
Where does this formula come from?
If you press the button in front of you
y=60
How can y + 3Y = 60?

In a subtraction formula, the sum of the subtracted, subtracted and difference is 256. What is the subtracted?

Subtracted = subtracted + difference
Subtracted + subtracted + difference = 256
It is known that 2 × subtracted = 256
Subtracted = 128
256÷2=128
A: the subtracted is 128
