Answer 2

Answer:

76 is the required number.

Step-by-step explanation:

Let the unit's digit of the number be x .

Then,the ten 's digit of the number is 13-x.

According to the question,

[10 (13-x)+x]-[10x+13-x]=9

[130-10x+x]-9x-13=9

130-9x-9x-13=9

-18x=9+13-130

-18x=22-130

-18x=-108

x=-108/-18

x=6

Unit's digit =x=6

Ten's digit =13-x=13-6=7

Number obtained =10 (Ten's digit)+Unit's digit

=10 (7)+6

=70+6

=76
