Answer:

The numbers are 7 and 35.

Step-by-step explanation:

Let the smaller number be x

Then larger number is 5x

If 21 is added to both the number

The larger number becomes twice the second number

5x+21 = 2(x+21)

5x + 21 = 2x + 42

5x - 2x = 42 - 21

3x = 21

x = 21/3

x = 7

The smaller number is 7

the other number is 5x = 5×7 = 35

Proof:

5x+21 = 2(x+21)

35+21 = 2(7+21

56 = 2(28)

56 = 56
