Question

The sum of the digits of a two digit number is 8 and the difference between the number and that formed by reversing the digits is 18. Find the number.The two digit original number is.....................​

Answer 1

Answer:

Step-by-step explanation:

let the digits be x and y

x+y = 8   ............(1)eq

Original number =>

10x+y= 8

Reversed Number = 10y +x

10x+y - (10y+x)=18

10x+y - 10y-x = 18

9x-9y = 18

x-y =2  ................(2)eq

add both the equation

2x = 10

x=5

x+y=8

y=3

the two digit original number = 10x+y = 53

Answer 2

Answer:

x+y=8

x-y=18

y=-5

x+(-5)=8

x=8+5

x=13
