4/7 is subtracted from a positive number and the result is multiplied by 7 to obtain the original number. What is the number?

1 answer:

6 0

Answer:

The original number would have been 2/3

Step-by-step explanation:

In order to find this, we first need to turn the word problem into a numerical problem. For the purpose of this, let the number equal x.

7(x - 4/7) = x

7x - 4 = x

-4 = -6x

2/3 = x
