QUESTION

The sum of two numbers is 18 and their difference is 12 ,then the two numbers are

ANSWER

let, the two numbers be x and y

ATQ,

x+y=18 ----------1

x-y=12 -----------2

So,

x-y=12

x=12+y ----------3

Putting value of x in Eq 1

x+y=18

12+y+y=18

So,

12+2y=18

2y=18-12

2y=6

y=6/2

y=3

we found the value of y

So, we can put the value in Eq 1

x+y=18

x+3=18

x=15

Therefore, the 2 number are 3,15
