The sum
of digits
digit numbers is 7.
The number obtained
on order of digits
is
greater than
original number by 9 . Find the number​

Answer 1

Step-by-step explanation:

x+y = 7. --- 1

10x+y+9 = 10y+x

=> 9x-9y = -9

=> x-y = -1. --- 2

from 1 and 2

By substition method

x = 7-y

7-y-y = -1

7-2y = -1

2y = 7+1

2y = 8

y = 4

Substituting in 1

x+4 = 7

x = 7-4

x = 3
