Let the numbers be x and y
From the given data, we get
⇒ 2 (x – y) = x + y
Given that one number x = 15
⇒ 2 (15 – y) = 15 + y
⇒ 30 – 2y = 15 + y
⇒ 15 = 3y
⇒ y = 5

Problem:
Twice the difference between two numbers is equal to their sum. If one number is 15, find the other number.
Solution:
Let's assume the other number as 'x'.
Given:
One number = 15
Other number = x
Equation:
Twice the difference between the two numbers is equal to their sum.
2(x - 15) = x + 15
Solving the equation:
1. Distribute 2 to x and 15:
2x - 30 = x + 15
2x - x = 15 + 30
x = 45
Conclusion:
The other number is 45. Therefore, option C) 5 is incorrect.
