Question

A positive number is 3 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?​

Answer 1

Answer:

Step-by-step explanation:

1 number=x

2 number=3x

So, 2(x+21)=3x+21

2x+42=3x+21

3x-2x=42-21

x=21

3x=63

Therefore, the numbers are 21 and 63
