numbers?​

Answer 1

Answer 2

Answer:

Answer is 35

Step-by-step explanation:

Let the other number be x

Given that,

A positive number is 5 times that number

:: Positive number = 5x

Now,

21 added to both numbers,

: New other number x+ 21

New positive number 5x + 21

Given that,

One of the new number becomes twice of the other new number

5x + 21 = 2 (x + 21)

5x + 21 = 2x + 42

5x - 2x + 21 = 42

3x + 21 = 42

3x = 42-21

3x = 21

X X =- 21 3

X = 7

: Another number is x = 7

Positive number is 5x = 5 x 7 = 35
