Let the number of votes received by the winning candidate be y, and let the number of votes received by the loosing candidate be x.
Now we have boil all the information down to two linear equations:
For the first, we know that the winning candidate (y) had 220 more votes than the loser (x). Hence, .
For the second, we know that the total number of votes that were cast was 810. Assuming that the winner (y) and the loser (x) were the only recipients of all these votes, we know that x and y added must be 810. Hence, .
Now we have two equations:
(1)
(2)
Substituting (1) into (2):
(2)

Now substituting the value of x in eq (2) back into (1):
(1)

From this we know that x=295 and y=515.
