You can put this solution on YOUR website! The two numbers are consective. This impies they are integers.
Let the first number be a. Then the second number is b=a+1.
The sum of two numbers = the differnce of those two numbers
Hence,
a+b = b-a (b is greater than a)
subtracting b from both sides,
a = -a
adding a to both sides,
2a = 0
a = 0
=====
b = 1
=====
Check
a+b = 0 + 1 = 1
b-a = 1 - 0 = 1
OK
