y+21,x+21

According to question

y+21=2(x+21)

5x+21=2x+42

5x=2x+21

3x=21

x=7⟹y=35✍️

Answer 2

Given:-

• A positive number is 5 times another number.

To find:-

• Find the number..?

Solutions:-

A positive number is 5 times another number.

• Let the one number be x.
• Let the another number be 5x.

21 is added to both the number, then are of new number become twice the other new number.

New number

• (x + 21)
• (5x + 21)

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

=> 5x + 21 = 2x + 42

=> 5x - 2x = 42 - 21

=> 3x = 21

=> x = 21/3

=> x = 7

• one number = 7

Putting the value of x in another number.

Another number => 5x = 5 × 7 = 35.

Hence, the one number is 7 and Another number is 35.
