X-5+5x-12=25
x+5x=25+5+12
6x=42
x=42/6
x=7
Answer:
The sum of two numbers is 25. One of the numbers exceeds the other by 9. Find numbers
<h3>here</h3>
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
⇒ 2x = 16
⇒ 2x/2 = 16/2
⇒ x = 8
Therefore, x + 9 = 8 + 9 = 17
Therefore, the two numbers are 8 and 17.
