Question

The Sum Of Two Numbers Is 25.Their Difference Is 15.Find The Numbers

Answer 1

Given :-

• The sum of two numbers Is 25.Their difference is 15.

To find :-

• Numbers

Solution :-

Let the required numbers be x and y

• According to first condition

→ Sum of two numbers is 25

→ x + y = 25 ---(i)

• According to second condition

→ Difference of two numbers is 15

→ x - y = 15 ----(ii)

Add both the equations

→ (x + y) + (x - y) = 25 + 15

→ x + y + x - y = 40

→ 2x = 40

→ x = 40/2

→ x = 20

Put the value of x in equation (ii)

→ x - y = 15

→ 20 - y = 15

→ y = 20 - 15

→ y = 5

Hence,

• Required numbers
• x = 20
• y = 5

Answer 2

Answer:

Question

The Sum Of Two Numbers Is 25.Their Difference Is 15.Find The Numbers

Answer

Let's consider the both number to be x and y

$(x + y) + (x - y) = 25 + 15$

$x + y + x - y = 40$

$2x = 40$

$x = \frac{40}{2} = 20$

Hence the value of x is 20

Value of Y =

$x - y = 20$

$15 - y = 20$

$y = 20 - 15$

$y = 5$

Thus the value of X and Y is 15 and 5
