In a subtraction formula, the subtracted is 15 / 7, so what is the sum of the subtracted, the subtracted and the difference?

In a subtraction formula, the subtracted is 15 / 7, so what is the sum of the subtracted, the subtracted and the difference?

It's 30 / 7
a-b=c
So B + C = a
So a + B + C = a + a
(a, B and C are subtracted, subtracted and difference respectively)

In a subtraction formula, the subtracted is 15 / 7, so what are the three numbers: the subtracted, the subtracted and the difference?
Try to make a formula. It doesn't matter if you can't make a formula

Are you sure it's the subtracted?
Sure, then
Let X be a subtraction, then x - (15 / 7)
So the answer is 15x / 7 (x - (15 / 7))
If you type it wrong, it should be a divisor,
Because divisor * quotient = divisor,
So the answer is 2 * 15 / 7 = 30 / 7

There is a subtraction formula. If the divisor, the divisor and the difference add up to 258, and the known subtraction is twice the difference, what are the subtracted, the subtracted and the difference?

Divisor = 258 △ 2 = 129
Difference = 129 (2 + 1) = 43
Divisor = 129-43 = 86
