Question

11. The sum of two natural
numbers is 25 and their
difference is 7. Find the
numbers​

Answer 1

Answer:

16 & 9

Step-by-step explanation:

Let the numbers are a and b.

Sum = 25 →a + b = 25

→ a = 25 - b

In question:

→ difference = 7

→ a - b = 7

→ (25 - b ) - b = 7 { a = 25 - b}

→ 25 - b - b = 7

→ 25 - 7 = 2b → 18 = 2b

→ (18/2) = b → 9 = b

Thus, a = 25 - 9 = 16

Answer 2

⭐ ᎯᏁᏕᏯᎬᏒ ⭐

Let the two numbers be x and y.

❄ Given:-

x + y = 25 ___________①

x - y = 7 _____________②

❄ Solution:-

Adding ① and ② :-

x + y + x - y = 25 + 7

2x = 32

x = 32/2

x = 16

From ①:-

y = 25 - x

y = 25 - 16

y = 9

The numbers are 16 and 9.
