A positive number is 5 times another number. If 21 is added to both the numbers, then one of the new numbers becomes twice the other new number. What are the numbers?

Dear Student

Let one of the positive number be x then other number will be 5x.
According to the question,
5x+21=2(x+21)
⇒5x+21=2x+42
⇒5x-2x=42-21
⇒3x=21
⇒x=7
Onenumber=x=7
Other number = 5x = 5×7 = 35
The two numbers are 7 and 35.
