fine mark as brainleast and also don't forgot to follow me
Step-by-step explanation:
The solution can be obtained by letting x be the 'tens digit', and y be the unit digit, so that the original number is 10x+y. Then 10x+y+18=10y+x, because the digits are reversed. This simplifies to 9x+18=9y, or x+2=y. Since the digits add up to 12, x+y=12.
