Question

The sum of two numbers is 15 and their difference is ,5

Answer 1

Given:

Sum of two numbers = 15

Difference between the two numbers = 5

To Find:

Let the numbers be x and y.

It is given that,

x + y = 15 -----(1)

x-y = 5 ---------(2)

Rearranging equation (2),

y = x-5

Substituting for y in equation (1),

$x + x - 5 = 15$

$2x - 5 = 15$

$2x = 20$

$x = \frac{20}{2} = 10$

$y = x - 5 = 10 - 5 = 5$

The two numbers are 10 and 5.

Answer 2

Answer:

The 2 numbers are 10,5

Step-by-step explanation:

• The concept of the equation and solution of the equation is used in this question.
• Let one umber is x and the other number is y
• The sum of 2 numbers is 15. This can be represented as

      $x+y=15$

• The difference of 2 numbers is 5. This can be represented as

      $x-y=5$

• Add both the equations.

      $x+y+x-y=15+5\\2x=20\\x=10\\y=5$

conclusio:

The 2 numbers are 10,5
