Let assume that,x and y are the two number.
So,
Two digit number =10x+y
And the reversed number is=10y+x
It's given
x+y=9........(1)
And also given that,
10x+y+9=10y+x
9x-9y= -1
(x-y)= -1.......(2)
By adding eq 1 and 2,we get
2x=8
x=4
Therefore,
The two digit number=10x+y
=10×4+5
=45
So,
Two digit number =10x+y
And the reversed number is=10y+x
It's given
x+y=9........(1)
And also given that,
10x+y+9=10y+x
9x-9y= -1
(x-y)= -1.......(2)

2x=8
x=4
Therefore,
