Answer 1

Answer:

7 and 35

Step-by-step explanation:

let first number be 5x

other number will be x

According to question

(5x+21)=2(x+21)

5x+21=2x+42

3x=21

x=7

5x=5*7=35

First number is 7 and other number is 35.

Answer 2

Answer:

-0

Step-by-step explanation:

Let first number be 5x

Another number be x

5x+21 = 2(x+21)

5x+21 = 2x + 42

5x-2x = 42-21

3x = 21

X = 21/3

X= 7

X= 7

5x= 35
