Question

Sum of two whole number is 45 and their differences is less than 10.the number of all possible pair is

Answer 1

hey there!!

let us take these two numbers as x and y

x + y = 45
x - y = 10

2x = 55

x = 55/2

x = 22.5

22.5 - y = 10

y = 12.5

That is one solution

Hope my answer helps!

Answer 2

let one of the no. be x
then other no. will be x+10

a/q x+x+10 - y= 45
2x+ 10 -y= 45
2x -y= 45- 10
2x - y= 35
