Question

the sum of two numbers is 2.5 . one of the numbers exceeds the other by 9. find the number

Answer 1

Let the first number be x.
So, other number = x+9
According to the question
x +x+9=2.5
2x=2.5-9
2x= -6.5
x = -6.5/2
x = -3.25

First number = x =3.25
Other number = x = x+9 = -3.25+9 = 5.75

Answer 2

hey theree !!

let the no be x and the other will be x+9

now, sum of no. = 25

x+x+9 = 25

2x + 9 = 25

x = 16/2= 8

so one no. is 8 and the other is x+9 = 8+9=17

hope it helps
