Let's call the number in the tens place A and the number in the ones place B.
The number would be AB or 10*A+B.
1.
If the number is reversed then,
2.
Let's simplify both equations,
1.
1.
and now eq. 2,
2.
2.
Let's multiply eq. 1 by 3 and add to eq. 2,
then we can solve for A.

Now use eq. 1 to solve for B.
1.

The original number is 36, the reversed order number is 63.
Check the answer.
36+27=63
63=63.
True statement.
Good answer.
