Call the consecutive integers n and n+1.


Keep in mind the definition of integers - ...-3, -2, -1, 0, 1, 2, 3...


Plug those values into the given relationship.


The greater (n+1) is (means =) 20 more than twice the smaller (2n+20).


n+1=2n+20 | subtract n from both sides and subtract 20 from both sides
-19=n, meaning n+1 = -18.


-18 is 20 more than 2 times -19. 2*-19 = -38+20 = -18.
