Answer:
Step-by-step explanation:
Given :-
Sum of 2-digit number = 8
If 18 is added to the number, the digits change their places.
To Find :-
The Number
Solution :-
Let one of the number be x
And the other number be 8 - x
According to the question
⇒ 10x + (8 - x) + 18 = 10(8 - x) + x
⇒ 10x + 8 - x + 18 = 80 -10x + x
⇒ 9x + 26 = 80 - 9x
⇒ 9x + 9x = 80 - 26
⇒ 18x = 54
⇒ x = 54/18
⇒ x = 3
One Number = x = 3
Other number = 8 - x = 8 - 3 = 5
Hence, the number is 35.
