Question

The sum of two numbers is 15. When one of these numbers is added to three times the
other, the result is 27. What are the numbers?

Answer 1

Respuesta:Answer:

Required numbers are 6 and 9

Explanation:

Let, two numbers are x and y

then,

Explicación paso a paso:→ Sum of numbers = 15

→ x + y = 15

→ x = 15 - y     ______equation ①

Now,

When one of those numbers is added to three times the other the result is 27, so

→ first number + 3 ( second number ) = 27

→ x + 3 y = 27

using equation ①

→ ( 15 - y ) + 3 y = 27

→ 15 - y + 3 y = 27

→ 2 y = 27 - 15

→ 2 y = 12

→ y = 12 / 2

→ y = 6

putting value of y in equation ①

→ x = 15 - y

→ x = 15 - ( 6 )

→ x = 9

Therefore,

Two required numbers are 6 and 9 .
