then one of the new numbers becomes twice the other new number. What are the
numbers?

Answer:
Step-by-step explanation:
let the number be x
therefore other number=5x
5x+21=2(x+21)
=>5x+21=2x+42
=>3x= 21
=> x=7
Answer:
Let the numbers be x and 5x
If 21 is added to both, we get x + 21 and 5x +21
Let 2 (x + 21) = 5x + 21
2x + 42 = 5x + 21
2x - 5x = 21 - 42
-3x = - 21
So x = 21/3 = 7
Therefore numbers are 7 and 35
