Question

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?​

Answer 1

Answer:

let the first no. be x

let the second no. be 5x

2x+42 = 5x +21

x =7

Hence one number is 7 and other no. is 35

Answer 2

Answer:

x=35, Y= 7

Step-by-step explanation:

let number be x

second number is Y

x = 5(Y)

x +21 = 2( Y + 21)

5Y + 21 = 2Y + 42

3Y = 21

Y=7

X= 35
