**Dennis**, Saturday, January 26, 2013 at 6:48pmOne equation would be:

x+y=69, correct? (add two integers to equal 69).

But then we know the integers are consecutive, so the second integer (y) is one greater than the first interger (x). So the next number after x is x+1

So we can say y=x+1

Then follow the train:

x+y=69

x+(x+1) = 69

x+x+1 = 69

x+x = 68

x=34

Perhaps you can use the above to determine which equation from your choices would work.
