Problems of this kind can be also easy solved mentally.
Below I show such a solution.
So, you have two numbers, whose sum is 41 and the difference is 5.
Mentally, diminish the greater number by 5.
Then you will have two equal numbers, their difference will be 0,
and their sum will be 5 units less than 41, i.e. 41-5 = 36.
But if two equal numbers sum to 36, then the numbers are 18 units.
Thus, your lesser number is 18, while the greater number is 18+5 = 23.
ANSWER. The numbers are 18 and 23, obtained MENTALLY.
Wow !
