Question

The different between two numbers is 18.If there sum is 86 what are the number

Answer 1

let the number be a and b
a-b=18
a+b=86
now adding two eq
2a=104
a=52 and b =34

pls mark it as brainliest

Answer 2

let the first no be x
let the second no be y
ATQ
x - y = 18
x = 18+y ......(1)

x+y = 86 ......(2)
18+y+y =86
18+2y = 18
2y = 86-18
2y = 68
y = 34

put the value of y in eq. (1)
x = 18+y
x =18+34
x = 52.

so two numbers are 52 and 34
