Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! We'll call one integer x.
The other integer is x+1. So we have:
x+x+1= 31
2x+1= 31 subtract 1, both sides
2x= 30 divide both sides by 2
x= 15 this is one number, and we said the other is:
x+1= 16 There you have it, those are your two numbers.
Proof:
15+16= 31
