Question

The sum of the digits of a two digit number is 14.if the number formed by reversing the digits is less than the original number by 18.Find the original numbers.plz answer in one variable
​

Answer 1

Answer:

86

Step-by-step explanation:

Let the two digit number be xy such that x+y=14  --->1

Its value = 10x+y

according to the condition, 10y+x + 18 =10x+y

9(x-y) =18⇒ x- y = 2 --->2

On solving equations 1 and 2 we get x = 8 ; y = 6

∴ the number is 86

Using one variable :

take y as 14-x
