becomes twice the other new no. find the numbers​

Answer 1

Answer:

Step-by-step explanation:

Let first number be "x"

Second number = 5x

AFTER ADDING 21 TO BOTH NUMBERS

First Number = x + 21

Second Number = 5x + 21

Here , 5x + 21 = 2 ( x + 21 )

5x + 21 = 2x + 42

5x - 2x = 42 - 21

3x = 21

x = 21/3

x = 7

First Number = 7

Second Number = 5 x 7 = 35
