Answer:

Hey Mate,✌☺️

$\mathbb \purple{\underline{GIV€N \: QU€STIÖN}}$

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?

$\huge \tt \pink{Answ€r}$

$\tt{\bold{\underline{x = 5y}}}$

x + 21 = 2( y +21)

x + 21 = 2y + 42

Substitute the first equation in the second one,

5y + 21 = 2y + 42

5y + 21 - 2y - 42 = 0

3y -21 = 0

3y = 21

y = 21/3 = 7

x = 5y

$\tt{Therefore, x = 5 × 7}$

$\huge \tt \red{\boxed{x = 35}}$

• Therefore, the number is 35.

Answer 2

Answer:

Let the numbers be x,y

y=5x

21 is added

The numbers are

y+21, x+21

According to question

y+21=2(x+21)

5x+21=2x+42

5x=2x+21

3x=21

x=7⟹y=35
