Question

I am thinking of 2 numbers. The first number is one more than twice the second number. The sum of the 2 numbers is 25. What are the 2 numbers?

A. 9, 16
B. 10, 15
C. 11, 14
D. 12, 13

Answer 1

The first number is 17 and the second number is 8.

Step-by-step explanation:

To solve this problem, let's denote the second number as 'x'. The first number is then '1 + 2x'. Since the sum of the two numbers is 25, we can set up the equation: (1 + 2x) + x = 25. Solving this equation, we get 3x + 1 = 25. Subtracting 1 from both sides, we have 3x = 24. Dividing both sides by 3, we get x = 8. Therefore, the first number is 1 + 2(8) = 17, and the second number is 8.
