Step-by-step explanation:
According to the question we can write as
x + y = 12 and also we can write as 10y + 10x - y = 54.
Which implies 9y - 9x = 54
y - x = 54/9
y - x = 6
y = 6 + x
Now on substiting this in x + y = 12 we get
x + 6 + x = 12
2x + 6 = 12
2x = 12 - 6
x = 6/2
x = 3
So the number is 39.
To check =>
Digit sum = 9 +3 = 12
Reversing the digit number will become 93 and 39 = 54.
Hence proof :)
