Answer 1

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 2

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
