Answer 1

Answer:

The numbers are 35 and 7.

Step-by-step explanation:

Given that:

A positive number is 5 times another number.

21 is added to both the numbers then one of the new numbers becomes twice the other new number.

To Find:

What are the numbers?

Let us assume:

A positive number = 5x.

Another number = x

After adding 21 to both the numbers:

Positive number = (5x + 21)

Another number = (x + 21)

Finding the numbers:

According to the question.

⟶ (5x + 21) = 2(x + 21)

⟶ 5x + 21 = 2x + 42

⟶ 5x - 2x = 42 - 21

⟶ 3x = 21

⟶ x = 21/3

⟶ x = 7

Numbers are:

Positive number = 5x = 5 × 7 = 35

Another number = x = 7

Answer 2

Answer:

Here is your answer

Step-by-step explanation:

let the smaller number = x

bigger number = 5x. -----(we need this.)

if 21 is added to both; 5x+21 = 2×(x+21)

5x + 21 = 2x + 42

5x - 2x = 42 - 21

3x =. 21

x = 21/3= 7

So the positive number is = 5×7 = 35

answer is 35
