[2.05] Choose the equation that could be used to find two consecutive integers whose sum is 69.

One 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

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.
