Question

19
A positive number is five times another
number. If 21 is added to both the numbers,
then one of the new numbers becomes twice
the other number. Find the numbers.​

Answer 1

Step-by-step explanation:

First number =x

second =y

x=5y. (1)

x+21=2(y+21)

x+21=2y+42

x-2y=21

from 1 x=5y

5y-2y=21

3y=21

y=7

x=5*7. from y=7 and x=5y

x=35

two numbers

7&35
