here is your answer

Answer 2

Answer:

63

Step-by-step explanation:

Let the first digit be:x

Another digit be:9-x

Sum of the digits:9

ORIGINAL NUMBER:10×x+1 (9-x)

NEW NUMBER:1×x+10 (9-2)

x+90-10x

-9x+90

New number=original number+27

90-9x=9x+9+27

90-3x=9x+36

90-36=9x+9x

54=18x

X=54/18

x=3

Original number:x+9-x

36

NEW number:9-x+x

63
