Question

Example 3. A number is 27 more than the number obtained by reversing its digits. If its it's
and ten's digits are rand vrespectively, write the linear equation representing the above statement​

Answer 1

Let the number digit of unit is x and ten number digit is y

Then number=x+10y

If we reversing number digit by ten number digit the number =y+10x

Given that the number is 27 more then  reversed number 

So(x+10y)−(y+10x)=27

Or x+10y−y−10x=27

Or 9y−9x−27=0

Or y−x−3= 0

Answer 2

y - x = 3

Step-by-step explanation:

let the ten's place be x and unit place be y

so the digit is 10x + y

now reversing the digits y comes to tens place and x comes to unit place

so the digit is 10y + x

ATQ

10y + x - 10x + y = 27

9y - 9x = 27

y - x = 3
