Find the number.​

Answer 1

Answer:

15 is the answer of the question

Answer 2

Answer:

45

Step-by-step explanation:

Let the unit place no. is y & ten place no. is x so the no. will be (10x+y)

given that x+y=9 .......(1)

acc. to the question -

10x+y + 9 = 10y+x

9(x-y) = -9

x-y = -1.......(2)

now by (1) & (2) we get

x=4 & y=5

So the required no is 45
