- The sum of two numbers is 25. One of the numbers exceeds the other by 9. Find the numbers.
Question 1:
The sum of two numbers is 25. One of the numbers exceeds the other by 9. Find the numbers. A. 8 and 17
Feedback Then the other number = x + 9
Let the number be x.
Sum of two numbers = 25
According to question, x + x + 9 = 25
⇒ 2x + 9 = 25
⇒ 2x = 25 - 9 (transposing 9 to the R.H.S changes to -9)
⇒ 2x = 16
⇒ 2x/2 = 16/2 (divide by 2 on both the sides)
⇒ x = 8
Therefore, x + 9 = 8 + 9 = 17
Therefore, the two numbers are 8 and 17.
